Are England trying to win this game?

I assumed that England would be trying to win this game on the basis that drawing the game involves facing more balls that could take wickets than if the game is won earlier than the planned finish.   At the moment their batting doesn't suggest ambitions of winning the game, but it's still within their grasp if Ali and Prior bat normally and stay together well into the final session.

In terms of psychology it would be almost as bad to be hanging on 8 or 9 down as losing....Cook's going to be under pressure either way.   A win would buy him the rest of the summer to prove he can score runs and captain effectively.
