Red Devils boss feared midfielder would quit
Sir Alex Ferguson says Anderson was considering his future at Manchester United last season as he was not a regular.
Anderson started just 10 Premier League games last term and it was thought he could leave Old Trafford during the January transfer window.
The Brazilian midfielder ultimately stayed at Old Trafford, but his season was cut short after suffering a cruciate knee ligament injury in a victory over West Ham in February.
Ferguson loves Anderson's determination and desire to play every game, however, he feels he lacks the maturity at 22 to understand his role within the squad.
"Anderson has an incredible talent," explained Ferguson. "He loves training and playing. He wants to play every game and train every day.
"But that is a problem for me because at 22 he has not got the maturity to understand we operate a squad here.
"When he does understand that, he will be a fantastic player here but last season he was talking about leaving because he was not playing in every game."
Understanding
Ferguson believes, if anything, the enforced break on the sidelines has helped Anderson understand his role at the club and that he will return an improved player.
"Maybe it is a good thing he has been injured for a spell because he can look at the situation," he continued.
"It is wonderful to see someone who wants to play every minute of every day. If you have someone with that enthusiasm, you have to be careful you don't check it to the point when you lose it.
"I didn't talk to him about leaving. I just let him get it out of his system. Maybe the injury has quelled the storm in his body because he came back here with the same enthusiasm and has been telling me he is ready to play."
