Speaking to reporters on Monday, Alonso said: "I was optimistic [about his signing]. His personality and competitive nature have pleasantly surprised me. He makes very few mistakes, he is very focused, he has great mental quality, great tactical and technical quality too, he is very complete. The instant impact he has had is surprising, it is fantastic news. We also have Fran [Garcia] and Ferland [Mendy] for that position, but his performance is excellent."
