It’s going to be a very tough one for him for sure, but I’m sure he will come back after the injury. Goalkeepers seem to have a long playing careers than outfield players, and had it been he’s an outfield player with this kind of injury I would say he should just retire but I think he’s still going to be back and continue playing but it depends on him to know if his body still carry’s him. Neuer is one of the best goalkeepers in the world whose career has spanned over a decade just like Buffon and most goalkeepers usually do peak from 30-40 years, but in Neuer’s case he has been an outstanding goalkeeper even before he turns 21 and he have shown that consistency till date.
It’s true that goalkeepers have a longevity in football, but the problem is that he usually have constant injuries, and that isn’t good for anyone, his been having constant injury and that could become a problem for him and Bayern Munich, Bayern Munich could be looking for a long term replacement as well, considering his age he should be getting some rest, as a footballer when you’re having constant injury and it’s coupled with his age, he should be considering retirement, and spend more time with his family, the notable thing is that it should be considered if his body can carry him, I wish him a quick recovery.
Goal keepers are really trying and because they hardly get injured, they tend to play longer than onfield players to the point that they almost forget retirement. Manual Neuer has given everything for the game and deserves to rest from active games, at least he shouldn't be starting games frequently again.
He's one goal keeper that has resigned continuously for the past 15 years since arriving the Allianz Arena same day as David De Gea of the then Manchester United. He has kept his consistency all years beyond his counterparts that he reigned with. I will be expecting him to retire after his contract expiration on June 30 next year.
However there's something I think is one of the reasons goal keepers don't retire so soon. That could be their earnings and low Ambassadorial deals compared to onfield players and star players.
About this, he is not also doing bad since he has been signed to many big endorsements that should have given him enough money to plan for his retirement. The club should be getting ready to go for a keeper in the January transfer window to support Urbig and give Neuer enough rest before his retirement.
