A lot of positives we can get from the last ODI. Actually the strategy did work that day. Both openers were pretty aggressive batsmen, yes, it's a pretty good strategy that had been used by the coach and the staff that day. Runs were flowing quite impressively in that little period of time. Dikwella and Sadeera had proved that they're in the game. Both batsmen got out by due to carelessness. For back of the length delivery Dikwella tried to hit it over the long on fielder which didn't work and Sadeera got out for the full toss which didn't work according to his merry way.
Furthermore, Apart from the batsmen. Amila Aponso had bowled pretty impressively by taking 3 wickets. All in all, spinners had come into a certain expectation during the last match. Slinga had some issues with the line and length during the last match. English batsmen studied Malinga pretty thoroughly though, hopefully he will do his maximum in the fourth ODI.
In addition to that, apart from Malinga, other pacemen had been got punished by the Englishmen during the last ODI. According to the match analysis it's proved that the line and the length are not so impeccable.
Finally, for the fourth ODI they gotta come up with good plans and erase the errors which they'd done during the last match plus gotta play a smart cricket in the fourth ODI.
