Tottenham goalkeeper Heurelho Gomes admits the players are struggling following their torrid start to the season.
The Brazilian admits the club's players are struggling mentally as they sit bottom of the Premier League table.
Gomes insists the quality is there but they need to start performing.
"I do not think the big problem is with the quality we have on the pitch," said the Brazilian.
"I think it is more mental at the moment. We are lacking in confidence, the game can be lost in your head.
"It is a difficult period for us at the moment.
"We lost another game against Udinese and everyone in the dressing room is down right now but we have to carry on because there are more games to play and Bolton is another difficult match.
"The formations are not an issue. What is important is the mentality of the players to produce a good performance and get us goals.
"We have great quality in this squad. We train well every day but on a matchday I do not know why this has happened."
