England take a 1-0 lead into the fourth ODI against Sri Lanka after the last game at Bristol ended in a no result due to rain.
So far in the series, Eoin Morgan's men have been on top in terms of bowling as they have restricted Sri Lanka to three scores below 300 and will be looking to do so once again on Wednesday.
Sri Lanka, on the other hand, know that their best is still to come and will be hoping that this game gives them the chance to show that they can compete with England in this form of the game.
Alex Hales - The opening batsmen is a key man for England as he dictates how their innings is going to go. Hales showed his best form in the second ODI, which England won comfortably, smashing his way to 130 not out. Hales followed up his hundred with a first ball duck in the third game but it can happen to anyone in this form of the game. Therefore if he can get going for England at the Oval there is a very good chance that the team will be able to wrap up the series with one game to go.
Dinesh Chandimal - The middle order batsmen is a key player in the Sri Lankan side as he comes in when the team are struggling and can get tough runs. Chandimal has so far made two half-centuries in three games in the series but has failed to push on for three figures which has proved how consistent he can be at this level. Chandimal played the last game with a hamstring injury but because of how important he is to the team he played through the pain, top scoring with 62.
The only real decision England will have to make going into the game is whether Moeen Ali comes back into the team after being replaced by Chris Jordan for the last game. The thought process will depend on the pitch as usually at the Oval it assists with spin which is when Ali will come in handy. Jordan though impressed in the last game so he has given the selectors and Morgan a headache coming into this game.
Sri Lanka have so far been consistent with their selection in the three games by not making many changes. It will depend though on whether Angelo Matthews and Chandimal are okay after their hamstring injuries for the game. The team though have been light on runs so they may bring an extra batsmen in for the game if the want too.
England likely line-up: Hales, Roy, Root, Morgan (c), Bairstow, Buttler (wk), Woakes, Jordan, Willey, Plunkett, Rashid.
Sri Lanka likely line-up: Perera, Gunathilaka, Mendis, Chandimal (wk), Mathews (c), Prasanna, Tharanga, Maharoof, Shanaka, Lakmal, Pradeep.
