The German international joined the club from Schalke last month, six months ahead of schedule, and he has impressed in his two substitute appearances to date.
Bale is delighted with his arrival and believes he will be just the man to push them on in their battle to land fourth spot.
"I'm sure he's going to fit in very well," Bale told The Evening Standard.
"Hopefully, we can get him into the team quickly and get him doing well for us.
"He's looked very sharp and he seems the type of player who could play well in a team like ours.
"At 22, he's a younger than me, too, so there is a lot of potential there and let's hope he can fulfil that at Tottenham. He speaks fluent English, too, which helps, and it means he has settled in straight away with the rest of the squad."
