Manchester United are running out of time to add to their squad.Jose Mourinho has previously gone on record stating that he wants more signings.An area that he has been willing to strengthen has been at centre-back.Mourinho has a number of options at his disposal, with Phil Jones, Chris Smalling, Eric Bailly, Victor Lindelof and Marcos Rojo all capable of playing at centre-back.But, Mourinho is clearly not convinced and has been trying desperately to bring in reinforcements.Toby Alderweireld and Harry Maguire were two names heavily linked with the club, but they have been unable to seal a deal for either.As a result, Man United have supposedly turned their attention to signing Yerry Mina from Barcelona.And multiple reports believe a deal is very close.Spanish publication Mundo Deportivo have reported that personal terms have all been agreed: the only thing that needs to happen is Barcelona to accept Man United's offer.But what do Man United fans think? They are on the verge of signing Mina, but are they happy with that?A poll has been created by the Manchester Evening News where United fans can vote on their preferred target.They have included four options: Alderweireld, Maguire, Mina and 'other'.Thousands of fans have now voted, and the results are extremely telling.

Alderweireld is a clear winner with 76% of the vote. Trailing well behind in second is Maguire, with 14%, while 7% are happy with the signing of Mina.

A handful of fans want the club to go in another direction, with names such as Raphael Varane and Samuel Umtiti being mentioned. Good luck with getting either of them.

So there we have it. 

Man United look as if they may well complete the signing of Mina before the transfer window closes next Thursday, but it is not a transfer that will go down particularly well with fans.

The centre-back debate has been going on for some time at United, with many pundits having their say.

Former Old Trafford favourite Dimitar Berbatov is one, and he wants to see Maguire make the move to Manchester.

"Manchester United need to sign a defender," he told Betfair. "Probably Harry Maguire from Leicester - he had a great World Cup, simply because of the way he controlled the ball and the vision he has on the pitch.

"He has the ability of passing like a midfielder and stays calm under pressure. He would be a great addition to the squad."
