Manchester United coach Louis van Gaal, who is already faced with an injury crisis, is sweating over the results of an X-ray on the foot of winger Angel Di Maria. The Argentine suffered the injury during the Albiceleste’s 1-0 loss to Portugal in Manchester on Tuesday following a challenge from Sporting Lisbon winger Nani, who is ironically still a Manchester United player. After the game, Argentina coach Gerardo Martino said, ''We don't think [the injury] is anything serious.”
