Tottenham midfielder Nacer Chadli admits he's never felt fitter.
Spurs boss Mauricio Pochettino is renowned for driving his players hard in training.
"(Pochettino) says before we start (training) that we have to be sharp," Chadli said. "He wants to make everyone sharp and be well trained.
"We always train with GPS. They are looking at players. If they get tired, they can see it on the GPS. The amount we run, they can check everything. You cannot cheat, or put the GPS on a cat. I've tried that!"
