Coutinho improvement is due gaining 5kg, says Bayern trainer

Bayern Munich's trainer says the reason for Coutinho's improvement is that he gained 5kg during Bayern training. Coutinho was one of the key players of Bayern Munich's extraordinarily good season.
The Brazilian trainer has explained that the improvement was surely because of weight gaining. He says it helped him improve his physical attributes and therefore being a better playmaker.
Fabio Mahseredjian has said, as per Diario AS: “After his time at Bayern, where he gained five kilos, four of which are muscle mass, he improved a lot physically.”
The Brazilian scored 11 goals in 34 appearances for Bayern Munich on a season-long loan spell at Bayern Munich last campaign and is now starring back in the Blaugrana’s starting line-up.
The former Liverpool star is now starring for the Catalan giants in a playmaker role and is forming a prominent part of the attack in Ronald Koeman’s new system.
He has been afforded a run in the team and is now a fundamental attacking player alongside Lionel Messi and Ansu Fati.
