Atletico Madrid midfielder Koke says Chelsea fullback Filipe Luis will be welcomed back by the squad.
Luis, after leaving Atletico a year ago, is being linked with a return this summer.
Koke said, "Filipe decided to leave and now he has the chance to return.
"If he arrives, there will be more competition, and that's good. We'll be a better team and fight for more things. Filipe is no traitor. As long as he plays and plays well there won't be any problem."
