PSV Eindhoven boss Ronald Koeman paid tribute to Alex after his super-show dumped Arsenal out of Europe and hinted the defender could be heading to the Premiership in the summer.
The rugged Brazilian defender netted at both ends at Emirates Stadium on Wednesday, with his late header at the right end proving enough to send PSV through to the quarter-finals of the UEFA Champions League.
Alex's future has been a hot topic of debate for some time, as it has always been rumoured that he was a Chelsea player on a long-term loan at PSV.
Koeman has confirmed this and hinted the defender could be on the move, provided he can secure a work permit.
"He is a player of PSV until the end of this season and after that we will be talking to Chelsea about the situation of the player," Koeman said on Sky Sports News.
Koeman added: "He's Chelsea's player and PSV rent him from Chelsea because he's still not allowed to play in England. We would like to keep him.
"I think Chelsea will be happy Alex scored against Arsenal."
