"It is difficult to explain why our home form is not good. We are controlling all the games, we are passing the ball well, controlling almost everything. But we pay for one mistake," said the Spaniard.
"There is no need to analyse the four holiday games. We deserved to beat Manchester City, we deserved to win against Wigan, while we beat Portsmouth and Derby.
"But we have lost four points in these games and it has meant the gap is bigger.
"There is no point being too critical of performances. We know we were much better than City and Wigan but we know we need to win, that is simple."
