Xavi will never tell the truth in press conferences. It's the same as with Pep who will praise even the biggest failure if asked, but if you never see him play u know what Pep thinks of him. They learn to protect the team from journalists and no matter how badly players or the team play, they will soften it in press. No need to quote his useless explanation for the press.
If you want to see how he really feels, just watch his interactions with the players in game. Raphinha for example yesterday felt Xavi's feelings.
