<text>  Manchester United defender Marcos Rojo is doubtful with a groin injury for Sundays crunch clash with Tottenham at Old Trafford. Manager Louis van Gaal revealed that the Argentina international will have a minor problem assessed before the game as the Reds prepare to take on Spurs in a key fixture in the battle for a top-four place in the Premier League. Manchester United defender Marcos Rojo picked up the injury against Arsenal on Monday night . Rojo started Mondays FA Cup quarter-final against Arsenal at centre-half to accommodate Luke Shaws return but reverted to the left-hand side of defence in the second half when Shaw was replaced by Phil Jones, before going off with 17 minutes left in the 2-1 defeat. However, Shaw should be available for the visit of in-form Spurs to Old Trafford but Angel Di Maria and Jonny Evans are both ruled out by suspension. Manager Louis van Gaal said Rojo has a minor problem and will be assessed before Sundays game . More or less, only Robin van Persie is injured, van Gaal told MUTV. That is a good sign when you have a defeat and all your players want to train and show the energy in the training session. Thats good to see. Rojo is a little bit injured. You have to take care of the health of the players. He has a minor problem. Maybe Ill take him out of the game against Tottenham Hotspur, but I have to decide.
