Manchester - Manchester United manager Louis van Gaal has confessed that Angel di Maria is struggling to adjust to English football after substituting him at half-time of United's 2-0 win over Sunderland.
After a promising start to his United career, following a club-record £59.7 million transfer from Real Madrid, the form of the Argentina international has dipped.
Di Maria has scored just once for United since the start of October and, after an ineffective first half against Sunderland at Old Trafford on Saturday, he was taken off at the interval by Van Gaal.
