I actually think this will benefit us in March/April.
The last 2/3 years the team's really come undone in some big games when we get shitty decisions, or seemingly unfair decisions and it's happened in this game as well - everyone's looking around like it's not fair, West Ham have been allowed back in the game.
If this happens half a dozen times before the Quarter-finals of the CL, they should go through it enough to just get over a bad decision and put it behind them, instead of dwelling on it.
