“Back to training with the group today,” Van Persie wrote on his official Twitter account.
“Was a great session. Happy to be fit and able to play again. Looking forward to my next game!”
The 31-year-old Dutch international, scorer of 10 goals this season, has not played for United since injuring his right ankle during a 2-1 defeat at Swansea City on February 21.
During that time, United have won five consecutive league games, meaning they will go into Sunday’s home game with City a point above their local rivals in third place.
