Barcelona SC centre back Frickson Erazo has admitted contact has been made between himself and Manchester United officials but that he risks losing concentration should he dream of a move to Old Trafford.

The Ecuadorian international, who has won 22 caps for his country, joined the national champions who claimed their 14th league title last season, in 2012.

And his impressive performances haven't gone unnoticed by United, who are understood to be tracking his progress, with club scouts having made contact with the 24 year old.

But Erazo is refusing to be caught up by the speculation linking him with United and Real Madrid.

Erazo says United have contacted him over a move.

"It's true that there was initial contact, but it will not help if my performance drops," Erazo said in the Daily Mail.

"I try not to think about this. It's really flattering that big European clubs are watching football in my country, but if you think about playing with Real Madrid or Manchester United you risk losing concentration."

Despite having Jonny Evans, Chris Smalling, Rio Ferdinand and Nemanja Vidic available to play at centre-back, United are seemingly looking to expand their defensive options in the form of the South American stopper.

One of those, Smalling, is quickly becoming a regular in defence amid injuries to the likes of Vidic, and having made 18 appearances this season, the England international is ready to make a major impact during the remainder of the season.

"No matter whether you are young or old you want to play in as many games as you can," he said.

"Luckily we are going well in all competitions. But when you get your chance, you need to take it. You don't give the manager an excuse to leave you out.

"It helps that we are in three competitions. It keeps everyone happy in that sense."

Squad rotation has long been part of life at Manchester United. And while Smalling admits he'd like to play every game, he's also aware of the system's benefits.

"You're at one of the biggest clubs in the world and the manager needs to do what he does. We are happy at the minute because everyone is getting games. Long may that continue.

"When you are injured you want to play. When you are fit you just want to play every week. But there is a large degree of patience required. You can't get too frustrated."
