Libyan starlet Sadiq El Fitouri credits Phil Neville and Paul Scholes.
El Fitouri was released by City in June 2014, only to then suffer injury as he attempted to find a club. He told United's official website that he has club legends Gary Neville and Paul Scholes to thank for now being on the books of the Red Devils.
He told Manchester United's official website: "I was out of action for a year and a half after I left City because I was injured and couldn't get a club. It was the worst time to get injured, straight after being released.
"After 18 months without playing, I was starting to lose hope. But in December , I phoned up Salford City and asked if I could train with them. They said 'Yes, come down' and I trained there for one month and played one game.
"Phil Neville was impressed and Paul Scholes too so they pulled me over to one side and said I could go to training at United the next day. Everyone knows who Neville and Scholes are and for them to have belief in me was really good.
"My trial at United lasted for a week and a half. During the first week, I remember I played an in-house game against Leicester. Warren [Joyce] was impressed and, a few days later, he said: 'Well done, I'd like to offer you a contract'. I thought it was all a dream as it happened so quickly."
El Fitouri signed with United in January 2015, and has become a regular in their under-21 side since.
The 21-year-old is a right-back, and has gone onto become capped by Libya, featuring in an African Nations Cup qualifier last year.
He has a big evening tonight as the Red Devils take on his old City side in the Manchester Senior Cup, a match he is relishing, and has a real opportunity to prove himself.
United are lacking options at right-back, and saw Guillermo Varela pick up a knock for the under-21s in his place on Monday night.
If El Fitouri grasps the opportunity to impress, then he could force his way into the reckoning for a first team opportunity at Old Trafford between now and the end of the season.
