Everton fullback Jonjoe Kenny admits he'd consider a return to Germany.
Kenny enjoyed a previous impressive spell on-loan with Schalke.
"I don't know what the future will bring. I can only say that I really, really appreciate the Bundesliga and the way it's played there and I can very well imagine playing there again," Kenny told Sport1.
"What counts for me is the project that the club is pursuing and how I can be integrated there.
"I want to become an integral part of a team and show game after game what skills I have, like now under Frank Lampard."
