Pirlo and Henry were disasterclass. Lampard struggled also. Zidane knew how to get the best out of his team during 2016-2018 but watching Real this season it seems like he has no tactic. What are we learning? Just because a player has a worldclass career dont make them good managers.
With Henry it was pretty obvious that he would probably be a terrible manager.
Pirlo I don't know, I thought it could go either way beforehand. Needs more time in order to evaluate him.
Of course we always knew that being a good player didn't guarantee being a good manager. There are many examples of that. But many, many examples of great players becoming great managers as well. Cruyff, Rijkaard and Pep were great players, so it is natural for Barcelona to have a tendency to look in this direction.
Xavi is one of the former players that I would expect most of as a manager. Not only because he was a very smart midfielder with leadership qualities, but mostly because he seems to be very much obsessed with the game, with a very clear and strong view on the basic way it should be played, not likely to be too much influenced by a single result or by other peoples opinions. I think that at this moment, Xavi would be the perfect one for Barcelona. If the results doesn't go his way, he would have to go, but he would make some necessary changes for the club to get back in the right direction.
