The Argentine defender has agreed a move to Manchester United but, unlike fellow arrival Angel Di Maria, does not have a European passport to smooth the switch
Manchester United boss Louis van Gaal admits that it is taking longer than he had expected for Marcos Rojo to secure a work permit.
The Argentine defender was confirmed as a United player earlier in August in a move that saw winger Nani rejoin Sporting on loan until the end of the season.
Rojo has been unable to make his debut for the Premier League club as yet due to red tape, with passport issues dragging the process out.
“Rojo is working on his permit because he has to go abroad for that,” Van Gaal explained to the press.
“The difference between fellow new signing Angel Di Maria and Rojo is that he has an Italian passport and Rojo does not.
“He only has an Argentine passport. Now he is abroad in Madrid to work it out at the embassy but it takes more time than we expected.”
Di Maria, a British-record signing from Real Madrid and a fellow Argentine, is poised to make his United debut at Burnley on Saturday.
