Manchester United legend Gary Neville believes it is the club's fault for allowing Ander Herrera's contract run down.

The Spaniard will be a free agent at the end of this season, with reports linking him with a move to PSG.

And Neville believes United do not have a proper system in place to stop such occurrences.

"I think the situation with him [Herrera] is that he's not likely to disrespect the club, he's been a brilliant professional here for the last few years,' said Neville during United's 1-1 draw with Chelsea.

"But all the speculation about him going to Paris Saint-Germain, Manchester United have allowed his contract to run down. If they wanted him, maybe they should have made the decision a little earlier.

"I think the other thing with Manchester United as well is that when you've got a change in manager every 18 months or two years, you might have one manager who fancies him, and another manager who says don't renew the contract.

"And then a new manager comes in but it's too late then and the player's contract has run down. That's why you need a club plan to take these sorts of decisions away from a manager. To enable the player to be protected and the value to be protected."
