If he wins us a CL as manager, he is in contention with Cruyff for most influential figure in Barcelona history.
Best player to ever play for Barca is gonna be Messi for a long time (probably forever), but the most influential category right now is Cruyff first and then Xavi and Guardiola second.
His winning mentality is something we have sorely missed since 2015.
What a huge difference to have a coach who has a clear idea of how he wants a team to play, to attack spaces, to come and receive the ball etc. What a time to be alive.
