Robin van Persie believes the negativity from Manchester United fans towards Alexis Sanchez could be ‘too much’ for the Chilean to handle.
The 30-year-old is pushing for a move away from Old Trafford and his agent has held extensive talks with Inter.
The Serie A club are keen to sign Sanchez but are refusing to pay half of the forward’s £400,000-a-week salary and have yet to reach an agreement with United.
Sanchez is yet to feature for United this season and Van Persie admits the former Arsenal player needs to ‘find his true happiness’.
‘Sanchez doesn’t look happy to me,’ Van Persie told BTSport.com.
‘I can’t properly judge it because I am not working with him but when I see him play I rarely see him smiling.
‘Of course, I get it: when you are playing you need to be serious and you want to win. ‘But after you score a goal you can smile, because that is the point of football.
‘We all play football because we like it and if you like something you should smile. ‘I think in the first couple of months after his move he was happy and he was playing well.
‘Mentally he needs to find that happiness again because if you are happy then you are fitter, you want to create and you want to have fun.
