The Chile striker is on-loan at Inter from Manchester United.
“I was with him in the hotel where he lived in Milan. For me he's a great player, with a long career, especially with his national team, he's very respected," Sosa told La Cuarta.
“He hasn't been given the right time, he can't play so little, he needs to stay on the pitch for several games, for ninety minutes. He needs time to go back to be the player he is.
“I'd keep Alexis for another year at Inter. He's a goal scorer, physically he's very well and still has a lot to give. He's a guy who has scored a lot of goals and will continue to do so."
