Actually whenever you lose,you can't start crying after that lost.It is the time to get re group and understand the mistakes which were responsible for defeat.
It is not the case that if you lose the match then you have to start changing the player which were unable to score.
For Example people are making fair argue regarding to Vaughn.He should have leaved team not because England lost or not because He was not able to score but because he has not acted like Vaughn,once He used to be year ago and He is nothing but a burden for a team.
There is no harm when you look at your mistakes and try to improve your combination.
