Kun struggles with weight and fitness when not playing, especially when it comes to pressing from the front.
To salvage this season, he needs a run of games to get him to match fitness PLUS being able to train every day. That can be hard with a knee that likes to swell up. Sure, players got fluid drawn off their knees and shunted back out back in the day, but Sports Science is far more complex and sophisticated today and inflammation us a sign of an underlying issue that needs resolving.
IF he can play, train, play for the rest of the season, then he has a chance of another year. Otherwise, a mutual decision to let him go home and finish his career (1 or 2 yrs max) with his childhood club would be a more fitting end.
He is the greatest centre forward the club has ever seen...until the next greatest centre forward shows up. Such is football.
He is, and shall remain, a REAL LEGEND for what he has done here, and I hope it can continue, but there is little room for sentimentality in the multi-billion dollar game today. Thankfully, the players understand and acknowledge this, as do the clubs who pay them extraordinarily well.
I hope we see Sergio back at his best this season, and perhaps even longer, but I fear those days are in the past and Sergio’s sun, which was dazzlingly warm and bright at times, is setting in Manchester.
