He spoke recently about how his anxiety contributed to his sub par form for Barca so I think he was really looking for someone to put an arm around his shoulder and convince him he's great.Of the three interviews from the new signings, he somehow seems to be the most genuinely happy to come to us. Good luck to him.
Silva as shown with Richarlison can be a bit of a father figure and he's seemed to have had a massive influence on this transfer along with all the others.
