Lionel Messi admits he doesn't understand Thiago Alcantara's decision to leave Barcelona.
The midfielder quit Barca for Bayern Munich last week.
Messi said: "Thiago decided to leave because he thinks he'll play more there. It's his decision, whether or not we understand it.
"Bayern is a great team and won the Champions League convincingly. With Guardiola they'll be even stronger.
Bayern beat us by too many goals for what we are as a team. It means we're hungrier this year."
