Brad Friedel's performances have made it impossible for Andre Villas-Boas.
But Barthez told Le Parisien: "Lloris is one of the five best goalkeepers in the world.
"He is faster than Friedel, he jumps higher and he is very strong mentally.
"What is happening now is incomprehensible, but I'm not concerned. He will become the centre-piece of the club. Hugo is a calm guy, a good worker. Tottenham will not let him stay on the bench for a long time."
