DonAK
President of FC Barcelona
No matter how each believes what truly happened behind the scenes with regard to Valverde, Messi could have and should have handled this better. He is the captain.
Honestly, if anything he should have reacted a long time ago. The club keep using the media to put the blame on the players all the time. Not to say the players aren't to blame, but the board/management is never under question for their poor planning and decisions.
