Chelsea goalkeeper coach Christophe Lollichon has his doubts over whether Hugo Lloris can handle life at Tottenham and in the Premier League.
The Frenchman first must find a way past veteran No1 Brad Friedel.
Lollichon said: "It's a unique championship for goalkeepers, there isn't an equivalent in Europe in terms of the aerial game, the timing of the strikers and the quality of the delivery on free kicks.
"It's a combat. To me, Hugo isn't showing the athletic qualities at the moment that will make opponents fear him."
