Arsene Wenger has paid tribute to Alexis' commitment and professionalism after he completed his move to Manchester United.
The Chile forward, whose contract with us was due to expire this summer, had been linked with moves away all season, but the boss says he never let it affect him.
"He’s a very professional player who has been committed until the last minute," Wenger told Arsenal Player. "In training, he was practising with full power, so I never questioned that. I never had any doubts about that.
"He's a world-class player who has contributed well to us and was a star here. I would like to thank him for his contribution here and I wish him well.
"He’s very attached to Arsenal and we were very attached to him as well, so it is not with pleasure that we lose him but it’s part of professional life."
