Wherever Jose Mourinho has gone he's left an impression for both good and bad reasons.

He won the Champions League with Porto in Portugal before moving to these shores to win Chelsea their first title in five decades. He moved to Italy to win the Champions League with Inter Milan and before coming back to the Premier League, he managed at Real Madrid.

His time in Spain was marred by a lot of controversy yet he still won La Liga as his rivalry with Pep Guardiola reached fever pitch. He managed some of the best players in the world at the Bernabeu as well as against them, and he's sure to be monitoring La Liga for any transfer targets now.

He signed Eric Bailly from La Liga but there is still time for more before the transfer window shuts.

So we've taken a look at what Spain has to offer to Mourinho at Manchester United, and think this FIVE could be of real interest...

Sergi Roberto

Sergi Roberto

Roberto is a fantastic young defensive midfielder but risks seeing his career stall at Barcelona thanks to the ever-present Sergio Busquets.

He may only be 24 but with Busquets only four years older he ideally needs to move away from the Nou Camp to reach his potential and he'd certainly play at United.

The Red Devils could do with a holding midfielder so it seems like a good match.

Toni Kroos

With Michael Carrick on the decline, the Red Devils need a new star in midfield to control the game and they don't come much better than the World Cup winner.

Kroos has one of the best passing ranges in world football and far surpasses anything United currently have in the play-maker role. He'd cost a bomb, but United have that kind of money.

Aymeric Laporte

Athletic Bilbao have done wonders to keep hold of Laporte but they surely can't have him for much longer.

The French defender suffered a nasty injury last season but that shouldn't put potential suitors, including United, off.

He reads the game far better than most defenders his age and would make a formidable partnership with Eric Bailly for years to come at Old Trafford.

Raphael Varane

Varane the man?

The French national team certainly have nothing to worry about at the back for the foreseeable future.

Varane and the aforementioned Laporte are two of the best young central defenders around but the Madrid man risks seeing his career falter behind Sergio Ramos and Pepe.

Zinedine Zidane is well aware of his talents, but if United make a big enough it could prove too tempting.

Mario Gaspar

Antonio Valencia has done well as a right back for United over the years but ultimately, he is being played out of position.

Jose Mourinho has come into the club aiming to get specialists into every position, it's the reason Wayne Rooney has reverted to being a forward, and so it would make sense that United go for a right sided defender.

Mario Gaspar is ideal, he's a good age, has Champions League experience and wouldn't cost the world either, time will tell.
