It has been reported that Fiorentina may cash in on Mario Gomez during the January market.
The Germany international striker is currently starring on-loan at Besiktas and Fanatik says he is interesting Manchester United.
United boss Louis van Gaal worked with Gomez at Bayern Munich.
Besiktas are desperate not to lose the Germany international midway through the season.
However, Fiorentina may yet sell should United firm up their interest.
