Zlatan wasn’t even the best player in LA! “As I’ve said, I don’t speak about players who do not belong to Real Madrid. I’ll only speak about the ones who are at Real Madrid and today is no different,” he said.”Did you see him today? Keylor is our goalkeeper. He’s here. There is no other goalkeeper we can talk about. Keylor, Kiko [Casilla], Luca [Zidane] and [Andriy] Lunin are the ones I can speak about.”Keylor is phenomenal. He’s been phenomenal all pre-season. He’s an extraordinary goalkeeper. He’s delighted to be with Real Madrid and we’re delighted to have him with us.”Goal understands that Chelsea will activate Kepa Arrizabalaga’s €80 million (£71m/$92m) release clause as they look for a replacement for Courtois.The move would break the club’s transfer record, set last season when the Blues signed Alvaro Morata in an initial £58m ($75m) deal, potentially rising to £70m ($90m), from Real Madrid.It would also make Kepa the world’s most expensive goalkeeper, less than a month after Alisson made the £65m (€73m/$85m) move from Roma to Liverpool.
