RB Leipzig coach Julien Nagelsmann has had a dig at Everton over their summer arrival Ademola Lookman.

The 21-year-old has made just one substitute appearance since returning to Leipzig in July.

“Some (new signings) still need a bit of development time because they did not have the regular game time at their previous clubs," Nagelsmann told Kicker.

“Experience has shown that newcomers usually take a little longer to get along with what I want.

“We have many video sequences with text attached. And then it is not easy if you can't speak the language yet.

“With a player like Ademola Lookman, who played very little at Everton, it takes more time than with Christopher Nkunku, who made 29 games at PSG last year. That's completely normal."
