Last week, Jose Mourinho revealed to Gary Lineker in an interview three players that he thought Manchester United sold too soon.

“Manchester United sold players that I would never sell and bought players that I would never buy,” he said.

“I would never have sold [Angel] Di Maria, Chicharito, Danny Welbeck – never, no chance.”

While Mourinho has raised a good point about the trio, the Red Devils are getting a reputation for letting players leave far too early.

Therefore, we’ve taken a look at eight players that the club allowed to leave far too early in recent years. While we blame Louis van Gaal for letting the majority of these leave, Sir Alex Ferguson was also guilty of failing to keep hold of some top talent.

Take a look:

Michael Keane | Burnley | £2m

Keane made his England debut against Germany earlier this week and has been very impressive for Burnley this season.

He was sold by Van Gaal in the summer of 2014 for just £2m but the 24-year-old is likely to attract some of the top Premier League clubs this summer.

Danny Welbeck | Arsenal | £16m

Sir Alex Ferguson rarely let one of his players join a rival club but Van Gaal seemingly didn’t care. Despite struggling with injury in recent years, United were left ruing the decision to sell Welbeck when he scored the winning goal to knock his former side out of the FA Cup just six months after leaving.

There’s no doubt that, when he’s fit, he would have been a very important player for United.

Paul Pogba | Juventus | Free

Pogba was a £89m mistake.

Ferguson wasn’t able to convince to Frenchman to remain at the club and the midfielder subsequently moved to Juve on a free.

Four years later and Pogba has become the world’s most expensive footballer with a £89m fee.

Ouch.

Gerard Pique | Barcelona | £5m

Allowing Pique to leave for just £5m was a massive error by Ferguson.

The Spaniard only played 23 times for United in four seasons before establishing himself as one of the best defenders in world football back at Barcelona.

At the age of 30, he’s still going strong.

Jaap Stam | Lazio | £16.5m

Ferguson was no stranger to falling out with his star players and his decision to offload Stam was seen as one of his biggest mistakes.

Stam was colossus at the back for United at it took a number of years for the club to eventually replace him in the form of Nemanja Vidic.

Angel di Maria | PSG | £44m

Di Maria lasted just one season at United - scoring four times in 32 appearances.

Just 12 months after spending £60m on him, the club allowed him to leave for £16m less than that.

Mourinho and the United supporters are definitely regretting that decision with him impressing for PSG in Ligue 1, while he destroyed Barcelona in the first leg of their last-16 Champions League tie.

Diego Forlan | Villarreal | £2m

While Forlan struggled for goals at United - scoring just 17 times in 98 appearances - he proved he was a top quality striker later in his career.

He impressed at Villarreal before moving to Atletico Madrid - where he scored 96 goals in 196 games.

To only get £2m for a striker of Forlan’s ability was a poor piece of business.

Javier Hernandez | £7m | Bayer Leverkusen

Hernandez was already a fan favourite at United and they couldn’t quite believe Van Goal allowed him to leave for just £7m.

He immediately showed the Red Devils what they were missing as he scored 26 goals for the German club in his debut season, while he’s registered 12 strikes this season.
