Former Liverpool striker Stan Collymore has advised Manchester United manager Jose Mourinho to sell Alexis Sanchez after watching him over the next few months.

The Chile international is the highest-paid player in the Premier League as the forward cost United not less than £500k-a-week of wages.

United boss Jose Mourinho has claimed in March that Sanchez would improve in his first full season. But the 29-year-old is yet to score a single goal for the Red Devils this season.

Therefore, former Premier League Collymore believes that the former Arsenal star needs to be sold.

“I’d be contemplating offloading Alexis Sanchez if I were Jose Mourinho,” Collymore wrote in his Daily Mirror column.

“Manchester United would get huge money for him and he’d fit hand in glove with Paris Saint-Germain, he’d score goals for fun at Bayern Munich, or be a hard-working conduit for Cristiano Ronaldo at Juventus.”

“There are times as a player you need to knock on your manager’s door and have the following conversation with him: ‘Gaffer, it’s not working.’”

“‘I know it’s not working. Shall we give it 10 games?’”

“‘Yes, let’s do that and if it’s still not working can we come to some sort of agreement?’”

“Managers get it, even though the money men might not agree.”

“What Mourinho needs to do now is give Sanchez a run of 10-15 games and tell him he’s the main man, and if it still isn’t working let him get on with his career elsewhere.”

“There’s still time to rescue it at Old Trafford, but not much.”

Sanchez moved to Old Trafford during January transfer window from Arsenal in a swap deal which involved Armenian playmaker Henrikh Mkhitaryan.

However, the former Barcelona attacker has since scored just three times for Mourinho side in all competitions.
