Bayern Munich midfielder Thiago Alcantara can understand Alexis Sanchez being unsettled at Arsenal.
Ahead of their Champions League clash, Thiago says former Barcelona teammate Alexis will always want to be competing for trophies.
Asked whether Sanchez had found his ideal playing style in English football, Thiago told the Daily Mail: "It's not about how he fits in the Premier League. He's good.
"It's just because he's good. And here in Germany, in England, in Spain, he's good.
"He would do great here or everywhere.
"He's a great player with a lot of technique and an instinct for goal. And all the time he was so competitive.
"He's a guy who wants football, who lives football, who breathes football.
"And he wants to win like we want to win."
