Norwood's on Fire
Yeah they will be affected in some way - that doesn't automatically mean it would be a negative. I would feel that I let those people down, and it would motivate me to do better.They'll obviously be affected in some way by 30,000 people booing them off the pitch when they're representing their country. I don't get how being one of the best 11 players in your country has any impact on that at all.
As for being one of the best players, well being able to handle the mental side of things is obviously part of that, given the microscope all of their football is played under. Rooney, for example, has dealt with worse things than being booed by his own fans when playing for Man U. Those who can't handle it wouldn't have made it in the Prem.
