“That’s what happens, it’s natural, when you have the opportunity to go to Wembley”
He said: “It’s a human thing. It happens to Watford and Crystal Palace. Those two teams, when they get through to the FA Cup semi-finals, I don’t think they won too many games.
“That happens, it’s natural, when you have the opportunity to go to Wembley. You’ve been working for eight or nine months and, all of a sudden, you drop by one per cent and that sometimes that affects you as a team.
“It’s not something you want, but FA Cup success affects your league form. Sometimes positively, sometimes negatively.
“It’s true, since the quarter-final our intensity has not been what it should be. If you look at our second half performance against United last weekend, that was us back to our intensity.”
