Everyone in the world knows what a selfish player Mbappe is and how due to said selfishness he can basically singlehandidly hold back a club from winning the CL as demonstrated by PSG. I think last year it was all speculation that his mere presence had upset the team dynamics and collective locker room vibe, but now maybe some of that is bubbling to the surface and while Carlo is well know to have used expert diplomacy to circumvent conflict throughout his carerr Xabi is still very much an unkown in dealing with big club issues and egos.
No yiu have to understand it's hurtful for a player to tell fans they're going to the second division man. It's just normal abuse and insults with the monkey chants and death threats. GET THICKER SKIN
