Guillermo Varela has had a strange Manchester United career, sometimes showing flashes of form which suggested he could have a long term future with the club. Varela arrived at Manchester United, initially just to train, as Sir Alex Ferguson was announcing his exit, and the Uruguayan’s time at Old Trafford has been as up and down as the club’s attempts to move on from Fergie.

A rather curious loan to Real Madrid’s Castilla squad came in 2014 with there being some claims Varela was finding it hard to settle at Manchester United. The defender also spent some time back in Uruguay.

A few appearances during Louis van Gaal’s final season as Manchester United manager suggested Varela could be an option at right back going forward. Jose Mourinho clearly had other ideas and Varela was loaned to Eintracht Frankfurt last summer.

Varela was injured for Frankfurt in his second match and had to undergo an ankle operation. He’s just returned for Frankfurt but unfortunately has had to again go under the knife.

The Manchester United owned player had been trying to play through pain since his recovery, but has managed just two more matches. Varela is being troubled by a screw inserted during the first operation, and whilst Germany’s Kicker explain that Frankfurt are impressed with his dedication to the cause, the pain is now too much to ignore.

Given that it’s only a small procedure to correct things, Varela is expected to make a quick return. The Uruguayan has a further year left on his Manchester United contract, and a decision will have to be made on his future in the summer.
