Zlatan wasn’t even the best player in LA! However, Skriniar’s agent, Karol Csonto, claims they are already talking about a new deal with Inter, even though his current terms are not due to expire until June 30, 2022.”We’re talking about it,” he told Tuttomercatoweb . “We’re working on it. It’s a subject we’ll be facing more intensively over the next few months.”Csonto insists Skriniar is enjoying life with Inter, where he has developed into one of Europe’s best young defenders since signing from Sampdoria last year.”He is happy with the Nerazzurri shirt, he is playing well, but he is aware there are some difficulties in Serie A,” he said.”Inter had won seven games in a row prior to the loss against Atalanta. He is doing well. I’m happy.”He is happy to be playing in the Champions League. Clearly, the goal is to grow with the team and improve day by day.”Skriniar said back in August that he never thought about leaving the club, though he did admit interest from Manchester United. Barcelona were also among the clubs reportedly chasing the defender this summer, though he now seems set to stay put with the Serie A side as they attempt to challenge Juventus’ dominance in the league. Inter sit third in the league, nine points back of unbeaten Juve and four back of Napoli. Jose Mourinho’s Manchester United sit in considerably worse shape, eighth in the Premier League and 12 points back of leaders Manchester City, who they lost to in a derby clash on Sunday. Mourinho has left no doubt over his want for a new centre-back for his side, with the club having shipped 21 goals in 12 games so far this season, but it now seems as though he’ll have to turn away from the Slovakia international.
