Chelsea striker Romelu Lukaku would be open to moving to Germany.
Lukaku has talked up the prospect of signing for Borussia Dortmund.
He said: "I still need to grow and for that I need to have time to play during the next season.
"A move to Germany? Schalke or Dortmund? Dortmund would be a good choice, especially as this club can still win the Champions League."
