Manchester United must do everything in their power to keep Angel di Maria at Old Trafford, but if they genuinely feel the Argentina international no longer wants to be at the club they should only agree to sell to Paris Saint-Germain on one condition.
Cash is of no real use to Manchester United; they have enough of it and it doesn't guarantee they could sign a suitable replacement for the former Real Madrid superstar, who has struggled in English football since completing his £59.7 million transfer last August but still has plenty to offer provided he wants to be at Old Trafford.
What they would require is another world-class central midfielder - one with a little more hustle and bustle about him - and who better than PSG's Marco Verratti.

Verratti bossed Matic and Fabregas
United should demand the Italy international in exchange for Di Maria. He was the best player on the pitch against Chelsea on Wednesday night and proved he would have no trouble cutting it in the Premier League despite his diminutive stature.
The 5ft 5in midfielder bossed Chelsea's midfield alongside his teammate Thiago Motta, totally outperforming Nemanja Matic and Cesc Fabregas in their own backyard.

Verratti could become the new Scholes at United
Verratti appeared to relish the challenge of competing against Chelsea with a man disadvantage; never shirking responsibility, and continually finding space and demanding the ball.
This is the type of instrumental performance Manchester United haven't witnessed from any of their central midfielders since Paul Scholes retired in the summer of 2013.
In fact, Scholes at his peak would have been proud of the performance Verratti produced at Stamford Bridge on Wednesday night.
The tenacious Italian, who rose to prominence during his spell with boyhood club Pescara before sealing a big-money move to PSG in 2012, is not only excellent technically but he also possesses that indefatigable energy to inspire a team.
United should only sell Di Maria if he wants to leave
He's a character - and Manchester United lack character right now. It was hoped that Di Maria would be the man to inspire Louis van Gaal's side, but the South American - barring an impressive opening few weeks - has looked a shadow of the player named Man of the Match in last season's Champions League final.
Manchester United fans - and Van Gaal - will be hoping Di Maria shows enough between now and the end of the season to convince everyone that he wants to be at Old Trafford, despite PSG's interest.
But if he fails to escape his current rut and decides he fancies a move to Paris, United should only be prepared to do business if it means securing the services of the pit bull-like Verratti in return.
