Yes, I think Tevez has been very difficult to compete with the young players who have the skill and stamina very good. I'm sure he could not compete in the world's top leagues. Tevez is now considering moving to China, he has two choices now to play in China with a high salary or retirement from football.
If you do a little research about his statistic, then you will realize that he still good on the pitch. Like what Zlatan said, that age is just a number for some great players, and Tevez get into the list too. Look at Zlatan, he is 35 yo but his stamina is still amazing, which he always plays in every match for Man United.
Miki is a good Midfielder, Even in Dortmund, he is number 1 midfielder in a club for a few years. No I think he is more than a really good midfielder, he is an awesome midfielder. I think he can be an option for the problem of manchester united this season and no need to sign another midfielder for January.
I still remember when I heard many Man United fans blamed him, and now they ve changed their mind lol. The same situation when Man United signed Martial. Yeah Mkhitaryan now has important role in Man United, I hope his injury isnt too severe.
