It is unwarranted and undeserved in my not so humble and incredibly biased and prejudiced opinion. Your opinion is he deserves that extension at the current salary - feel free to believe so. I'm not saying you're wrong, but neither am I. After all, opinions are subjective. You could objectively argue that he's having a career year, but I could objectively counter by stating that he was dogshit for 3 years, conning the club and doing absolutely nothing. Had he been working for a top tier organization, he would have been shitcanned a long time ago. Unfortunately, that's not how it works in football.
Ruben Neves, Youri Tielemans, and Konrad Laimer from the players on the list with expiring contracts in 2023 and 2024.
Anyway, I still love you
