#2 Manchester United - Marcos Rojo

Louis van Gaal’s arrival at Manchester United saw many relatively unknown players move to Old Trafford. Marcos Rojo was one of them. The Argentine defender is capable of playing anywhere along the backline and hence was seen as an asset by LvG.
Rojo was initially deployed in the left-back slot, but gradually, he has been drafted as a centre-half too. Even Jose Mourinho seems to like the lad, as he trusted Rojo enough to play him as the centre-back for the better part of last season.
This generally gives us an impression that Marcos Rojo is a quality centre-back. Obviously, to start for Manchester United in such an important position is an achievement of sorts. However, over the past few seasons, Rojo has been a touch too rough and sloppy with his game.
In the game against Arsenal last month, the Argentine made several unnecessary tackles quite early in the game. He tends to get more physical than required and ends up paying the price for it. Rojo has featured in six Premier League games this season and has been booked five times.
Jose describes him as a "disciplined player with an aggressive nature", but one who has followed him closely will know that Rojo gets malicious with his challenges at times. He is also known to over-commit at times, thereby taking a huge risk of leaving empty spaces behind him, and suffering from it too.
Though Rojo is a brave player who is always willing to give his all for the team, he certainly needs to bring in some discipline in his game to become a regular starter for such a big club.
