Obviousely a little nervous but lets have some perspective here - we have lost 2 games in the league at home in the last three seasons, once against Chavs were we had to change the team at the last minute and against sunderland last season - can't think on any others.
West Ham are a poor team with nothing to play for, other than spurs last week ( 10 men, and still had plenty of chances) they have conceded in 14 prem games, and shipped 9 against us at ours. If we score 1 its very unlikely with their 10 minutes possesion they will score 2.
I expected it against QPR and that game is probably all that is making people nervous, and i expect a comfortable win on sunday.
If it was the other way round and Liverpool were at home to WH would anyone really expect them to blow it?
