Neville has led Valencia in eight league games without recording a win

Gary Neville says watching his Valencia side get demolished 7-0 by Barcelona at the Nou Camp was one of his "worst experiences" in football.

Wednesday's loss in the Copa del Rey semi-final first leg has increased the pressure on Neville, who is without a league win in eight matches.

"I am not going to sleep well tonight," said the former England player, who insisted he would not quit as manager.
