Argentina international Marcos Rojo has confirmed he will join Manchester United, bringing an end to a long-running transfer saga.

The 24 year old has been at the centre of a dispute between his club Sporting Lisbon and Doyen Sports, who own 75% of the player's contract after financing his move from Spartak Moscow in 2012.

In an attempt to force through a move to United, Rojo – who played for the Argentina side that reached the World Cup final in Brazil – handed in a transfer request and refused to train with the Portuguese club.

The full-back missed the opening game of the season against Academia and was fined for his actions before being forced to publically apologise however the player has been seemingly allowed to move to Old Trafford to become the club's third significant signing of the summer

"It feels like a dream, to be a Manchester United player," he told ARG Radio Continental. "Leaving Sporting wasn't easy. I am very proud of having the chance of working with Van Gaal.

"[Juan Veron] told me about them when we played for Estudiantes."

"There was a misunderstanding," Rojo said regarding his transfer request. "I never wanted to do something wrong at Sporting as I have always been very thankful to that team that gave me many chances for playing in Europe.

"If I made a mistake, I have already apologised because I didn't want to hurt the feelings of anyone at the club."

Following the opening weekend defeat to Swansea City, the news comes as a huge boost for United who will hope the addition of Rojo can spark a series of high-profile late additions during the final two weeks of the transfer window.

Manager Louis van Gaal has hesitated in adding to his squad, only signing Ander Herrera and Luke Shaw so far this summer, but admitted following defeat in his first match at United boss that new signings were needed.

The 20-time English league champion have been linked with deals for Juventus midfielder Arturo Vidal and Real Madrid's Angel di Maria.
