Lucas Moura is the only absentee for Tottenham's Champions League opener with Marseille because of a calf problem.
Boss Antonio Conte says the tournament is the best way to show the team are going in the right direction, but says it is "unthinkable" they will win it.
Spurs are unbeaten in the Premier League after six games this season.
"We have to play with great ambition, passion and will to be a protagonist in this competition," he said.
"This tournament is the most difficult in the world, but at the same time it's a great opportunity for us to show we are going in the right way and taking steps forward.
