Manchester United defender Marcos Rojo happy to deputise for injured Luke Shaw

Marcos Rojo is content with his status as Manchester United's replacement for Luke Shaw after the England international's harrowing double leg break ruled him out for much of the season. The 20-year-old is not expected to return until 2016 after picking up the blow against PSV Eindhoven in the Champions League and it has forced manager Louis van Gaal to shuffle his pack in the absence of a genuine stand-in.

Since the 3-0 thumping by Arsenal, Rojo has started the club's last six games at full-back during which time they have conceded just once. The Argentina international's form has underpinned that defensive steal which sees Van Gaal's side as contenders for domestic and European success this season.

Rojo has otherwise endured a season in and out of the United first team, with a late return from the Copa America being compounded by a series of injury concerns that has restricted him to just four Premier League starts. However, the 25-year-old has benefited from the injury to Shaw and he is delighted with the opportunity.

"I'm going to put in all the work necessary so I can be on form to help out the team in that position," Marcos told the official United website. "What happened to Luke is a real shame and a player never likes to get into the starting team as a result of an injury to a team-mate, but that has been the case with me and now I have to get my head down and work hard in that role.

"When it was time to move over and play at full-back, I had to work at it, both for club and country. It's something I continue to work on in training, so I can keep on improving. Crossing the ball well, getting to the byline and helping to finish off a move are all key things I need to do in my position.

"Without a doubt, I have a lot ahead of me to experience in the game. But I try to play every game in the same way, doing my absolute best whoever the opponents are. The [United] manager has said I still have a lot more I can show as a player, and he is someone who is very knowledgeable about the game. All I try to do is train hard every day and keep growing and learning a little bit more."
