ENGLAND-WOES: England's bowling has been poor in T20-cricket for a while. It was exposed by AB de Villiers and Hashim Amla at the Bidvest Wanderers Stadium, where they hammered 125 runs off 55 balls for the first wicket. And against the West Indies, England was blown away by a Gayle-force.
SPOT ON: South Africa need to improve their run-rate in the middle-period between the 6th and 12th over, says Kepler Wessels, a former South African opener. Alviro Petersen, a former South African opener, has recently uttered the same sentiments, claiming South Africa is too old-school in their approach in the middle-period. They need to accelerate in that phase, instead of just rotating the strike.
SPIN-ATTACK: Australia showed South Africa the way in attacking the spinner in the middle-period. South Africa must do this against England.
MORRIS OR WIESE: Many David Wiese-fans would bemoan his absence, but Chris Morris has got the X-factor with bat and ball. He was sensational for the Rajasthan Royals in the Indian Premier League last year, and can be a factor at the start or at the end.
WINNING TOTAL: South Africa has improved their scores significantly the past 15 months and is playing with greater freedom. They won't be happy with any total less than 190 at the Wankhede Stadium. They should not be, as England possess the batsmen to hurt anyone, yet their attack is below-par and lack the experience that Stuart Broad and Stephen Finn could have provided.
ATTACK ON INEXPERIENCE: South Africa will want to attack the inexperienced bowlers of England, David Willey, Reece Topley, Chris Jordan, Moeen Ali, Adil Rashid and Ben Stokes. There's talent aplenty, but they are not seasoned warriors.
AB AT THREE: Will AB de Villiers bat at number three? It might depend on the match-situation.In 2015, the Royal Challengers Bangalore used him at number 5 initially and it caused an outcry. He was moved to number three and was destructive there. AB made 513 runs for Bangalore and he might just fulfill that role again against England in Mumbai.
WILLEY ON TOP: David Willey started well, conceding just two runs in his first over. South Africa looked slightly circumpspect. Reece Topley, a left-arm swing bowler, will start from the other end.
SHOT: Quinton de Kock opens the blade and hit a wide delivery over square cover for six off Reece Topley. Great shot. He hits a similar shot two balls later for four. Chris Gayle went after Topley early on, and South Africa is intent on doing the same.
BEAUTY: Quinton de Kock was a tad frenetic off the first two deliveries by David Willey in his second over, but connected with a straight six followed by a shot past mid-on for four. De Kock is off to a rollicking start and South Africa has moved to 27 without loss. England requires slower varieties. De Kock strikes a square cut to power the Proteas to 31 after 2.5 overs.
MASSIVE: Quinton de Kock produces his best shot of the evening, a 91-metres square drive over square cover off David Willey. England has been too predictable. There has been no slower varieties, short deliveries or Yorkers, and De Kock is making them pay. He slashed 20 runs in the previous over by Willey. England's line is poor, and De Kock is cashing in.
AMLA SURVIVES: Reece Topley drops Hashim Amla at mid-off on 10 off Moeen Ali. It was a regulation chance after Amla had struck two fours in that over. England is bleeding, physically and emotionally. The fifty comes up after 3.5 overs.
WHAT A SHOT: Quinton de Kock has been all power before he played a classic late cut off Moeen Ali for a splendid four to power South Africa to 50 without loss in 3.5 overs, the fastest start yet for South Africa in a T20-International. That was a shot that just underlined his magnificent timing and hand-eye-coordination.
AMLA JOINS CARNIVAL: Hashim Amla joined the batting carnival by hitting three successive fours off Chris Jordan and then a six. England is straying. Their line is below-par. They either give Amla width, or bowl to straight to him. That's why there is carnage. Amla is on the charge and South Africa is toying with England. South Africa has struck 68 without loss after 4.4 overs.
WHY THE TSUNAMI OF RUNS? South Africa scored 72 without loss in the first first five overs because England offered so much width, but you still have to put it away, and Quinton de Kock and Hashim Amlah have been relentless. De Kock struck 40 off 17 balls and Amla hammered 37 off 16 balls.
POWER-PLAY EXCELLENCE: South Africa has struck 83 in the first six overs, which is just 5 less than the 88 they hammered in six overs against England when they won comprehensively by nine wickets. What a massacre!
DE KOCK-FIFTY: Quinton de Kock strikes a beautiful four between mid-on and midwicket to complete a half-century off 21 balls, which equals AB de Villiers as the fastest half-century at T20-level yet by a South African. It is De Kock's quickest half-century yet.
ENGLAND STRIKES: Quinton de Kock is caught at deep midwicket by Alex Hales off Moeen Ali for 52 (off 24 balls) when he tries to go after a quicker, flatter delivery. It was the right strategy by De Kock, who continued his belligerence. AB de Villiers walks in. South Africa want to target the middle-overs. South Africa slips to 96 for one after 7.1 overs.
CLASH OF BEARDS: The crowd at the Wankhede Stadium is appreciating the beard of Hashim Amla and the England-bowler Moeen Ali and displays a placard with the words "Clash of the Beards". But Nasser Hussain says Amla easily has the biggest beard of the two.
SHOT: AB de Villiers goes after Adil Rashid and hits two sixes in a row off Adil Rashid. South Africa has clearly decided that the slow bowlers will have to go in the middle-period. This is an important tactic by South Africa.
ENGLAND STRIKES: AB de Villiers is caught off a superb and thoughtful delivery by Adil Rashid, who bowled a slider and lured De Villiers into an attacking stroke, but he edges it and is caught in the covers by Eoin Moran for 14. South Africa is on 114 for two after 9 overs.
BOOM! Hashim Amla uses the depth of his crease very well to pull Moeen Ali with ferocious power for six as he completes his half-century off 25 balls. It is great the Amla is either moving a foot forward or just edging back into his crease deeper. That manipulation of the crease helps him to get on top of the bowling. South Africa moves to 125 for two after 10 overs.
AMLA-APPROACH: It is clear that Hashim Amla has taken it upon himself to play a more aggressive game than usual, with Faf du Plessis only getting settled in.
AMLA TRAPPED: Hashim Amla is trapped in front for 58 off 31 deliveries by Moeen Ali. He tried to get in under the ball and slog-sweep it square for a six, and misses. It is an easy decision. JP Duminy walks in. This is a crucial period for South Africa, because both Faf du Plessis and Duminy tends to take time to settle in at the crease.
SINGLES NOT ENOUGH: South Africa is temporarily slowing down and scoring singles. England is restricting South Africa, but the Proteas cannot allow to take the foot off the accelerator. Singles are not enough. They cannot afford to move sedately to 180. The score is 139 for three after 13 overs. They require at least 200.
DUMINY ACCELERATES: England experiments with Joe Root, but JP Duminy strikes two successive fours of which the first was due to poor fielding at long-on by Alex Hales. The over produces 13 runs. It seems as if the business-end as started for South Africa as the Proteas to move to 152 for three after 14 overs. They cannot afford to slow down now, as David Miller and Chris Morris are due to be in next.
