Former Inter Milan striker Jurgen Klinsmann feels his old team are yet to get out of third gear this season.

Klinsmann says the Nerazzurri have so far underachieved.

He said, "At this point of the season, I didn't expect the -10 from the top in the league. That's a lot, but it's like as if Inter haven't exploded definitively yet."

Klinsmann also says Inter Milan must keep hold of Germany fullback Robin Gosens.

"Robin mustn't leave, he doesn't need to go on loan elsewhere. He just has to fight, he's a player at Inter's level and I'm sure of that." he added.
