Meh, he could probably have put a slighty stronger side out, but ringing the changes is fine at this stage. Anyone complaining too hard just isn't paying attention.
If you lose the league and Chelsea, City, Spurs and Arsenal get knocked out in the next round though it might look a bit daft to have not tried a little harder to stay in. It might only be the FA cup, but it's still better than nothing at all. It'd be nice for us to win it this year tbh. Equal arsenals record.
