Atletico Madrid midfielder Koke says Chelsea striker Alvaro Morata would be welcome at the Wanda Metropolitano.
After Sevilla signed Barcelona striker Munir El Haddadi, Atletico could have a clear run towards Morata, formerly of Real Madrid.
"Morata is a great player, I've always said that," Koke said at an Atletico Foundation event that is raising awareness about prostate cancer.
"I played with him in the Atletico academy and then circumstances changed [Morata went to Getafe for one year before joining Real Madrid's youth setup].
"It is true that I've heard this rumour, but he is not our player; he is Chelsea's and we have to respect them.
"Right now, we are the players who are here and we shouldn't be thinking about players from elsewhere.
"If he comes, he will be welcome."
