Sampdoria president Massimo Ferrero admits Eder could leave this summer.

Eder is currently recovering from a knee injury.

"Would I take €10m for Eder? I am keeping a tight hold of him, but we do have an agreement," Ferrero told Sky Sport Italia.

"We made a pact that if there's an offer he can't refuse, he will go where his heart takes him and I will follow my wallet."
