The Portugal international still has over a year left on his current contract, however talks over a new deal have stalled recently and his future has been in doubt for some time.
It has not been the best season for Nani so far either, with his performances not quite being up to scratch and with the likes of Antonio Valencia and Ashley Young in the squad, it may be time for him to move on.
Serie A giants Milan are weighing up the possibility of making a move for the midfielder, but are not likely to launch their bid in January as it could cost them more than they value him at.
Nani played in the 3-2 defeat in the English Premier League to Tottenham Hotspur at the end of September. However, a poor performance and a reported training ground bust-up after this saw him dropped for the next two matches against Newcastle United and CFR Cluj.
If Milan want to secure his services though, they may have to make a bid sooner than the summer as a number of teams are said to be monitoring his situation.
