Tottenham goalkeeper Hugo Lloris admits the club will need to show all their fighting qualities if they are to secure a top four finish and reach the Champions League.
The north London club moved just one point behind Chelsea in third place with an impressive 1-0 win over West Brom at the Hawthorns on Sunday.
Despite failing to sign another striker in January, Andre Villas-Boas' side have shown they are still one of the best teams in England this season and have suffered just one defeat in their last 13 games.
Lloris knows his team will have to show all their mental strength if they are to maintain their position in the top four and ensure they finish above Everton and Arsenal, who are pushing them all the way for a Champions League spot.
The French star said: "We have to continue to be strong because Arsenal are there, and Everton as well.
"It was a good opportunity to close in on Chelsea and we took it, so it's an important win for us.
"West Brom play good football and have two strikers with good movement but we were strong and of course the red card [for Goran Popov] changed the game, but we deserved to win.
"Gareth (Bale) was decisive and scored a fantastic goal but I thought the whole team did well. It was about team work."
