Gallas says Andre Villas-Boas’ Spurs side, who face Norwich in the Capital One Cup tomorrow, are capable of achieving a clean sweep of trophies.
He said: “We can win all the trophies and finish fourth, why not? We have to be strong in the heart.
“The manager is a competitor, he is a warrior, he wants to win everything. So every game we have meetings and it is the same, he wants to win, win, win. We will try to win all competitions, but know it is difficult.
“That is because we play so many games and some players are very tired. They play for the national team as well, so it is not easy.
“All the players know what they have to do. If they are tired on the pitch, then they play with their heads. It is important for us to try and win every game.”
