Manchester United are monitoring Real Valladolid defender Mohammed Salisu.

The Mirror claims that the defender has an ever-growing list of suitors with a number of clubs interested due to a bargain release clause of £10m.

The Red Devils are one of Salisu's possible destinations this summer but they face competition from a host of Premier League clubs.

Everton and Southampton are also credited with an interest in the 21-year-old.

The Ghanaian has already turned down beady eyes from Rennes in France but Atletico Madrid and teams in Italy remain in the hunt.

GIVEMESPORT'S Matt Dawson says...

It will come as no surprise to see that Atletico are interested in the centre-back. 

After all, one of his best performances of the season was saved for Diego Simeone's side. 

Back in October, the colossal 6 foot 3 defender put in a monstrous display as he bullied Diego Costa off the park - an achievement that is by no means easy.

In a 0-0 draw, Salisu made three tackles, won three aerial duels and produced four clearances.

Costa, on the other hand, was dispossessed once, had just two shots and registered a pass success rate of 53% - it simply wasn't his night.

On that evidence, the bullish approach that Salisu takes would certainly benefit United, a team not really renowned for being too aggressive defensively. 

Harry Maguire is clearly in need of finding a defensive partner and at just £10m, Ole Gunnar Solskjaer could find his answer. 

With Everton and the Saints also in the hunt, it may not be the world-class player United fans want but it's important to remember the Ghana international is just 21.

His performance versus Atletico showed what he can do when at his very best - if he can be nurtured further he could become a force to be reckoned with.
