Manchester United boss Louis van Gaal has concerns over Argentine defender Marcos Rojo, according to the Daily Star.
Rojo has endured an indifferent opening to his Old Trafford career, having struggled to maintain his fitness throughout the course of the campaign so far.
As well as struggling to stay fit for a consistent period of time, the versatile Argentine has failed to hit his best form under the Louis van Gaal regime.
And now, with Manchester United's defence having looked vulnerable all season long, it has been reported that Van Gaal hasn't been completely impressed with the defender, but is willing to give him time to settle to the English game.
Having signed from United from Portuguese outfit Sporting Lisbon, it's certainly not surprising that it's taking the 24-year-old time to prove his credentials at the Theatre of Dreams, but he will now be hoping to step up sooner rather than later.
With the player now back in training, it remains to be seen as to whether Van Gaal will hand Rojo a starring role as the Red Devils travel to Loftus Road this weekend to take on struggling QPR.
Return to form?
Along with the Argentine, the likes of Jonny Evans, Phil Jones and Chris Smalling will also be hoping to feature, whilst wing-backs Rafael da Silva, Antonio Valencia and Luke Shaw could all be in contention for a starting place.
After Manchester United were beaten this past weekend against Southampton, the club will be desperate to bounce back against Harry Redknapp's side on Saturday.
There's no doubt about it, the club's focus will now turn to qualifying for next year's Champions League, with things very tight towards the top of the division. United are currently sitting in fourth place - just one point ahead of rivals Arsenal, who sit in fifth. It certainly looks set to be an interesting battle for the final European places this season.
