The Argentine attacker admits that he hasn't lived up to expectations since his hot start to life at Old Trafford.
Di Maria, 27, sealed a £59.7 million switch from Real Madrid to United in August after four successful seasons in the Spanish capital, before making an immediate impact with three goals in his first five Premier League games.
The Argentina international has been on a 13-game top-flight scoring drought since October, however, and concedes that he is still attempting to adapt to English football after five months at Old Trafford.
“I've had a couple of games where things haven't gone as well as they could have. I think it is part of that settling-in process to the English game," he told MUTV.
"I started off quite well but I think that made expectations rise and everyone thought that I would just carry on the same way but football is like that; sometimes you have ups and downs.
"It took me a while to settle in fully in each of the countries where I have played before but I just have to keep working hard and focusing on what I want, which is to do as well as I possibly can.”

Di Maria moved to Madrid from Benfica in 2010 and made a total of 190 appearances for the Spanish side, chalking up 36 goals and 72 assists, before helping the team to the Champions League title - their 10th European crown – in his final season.
His production in the goal department might have been disappointing during his time in Manchester thus far, but the 57-times capped attacker has managed a team-leading nine assists in all competitions, including three in his past two league games.
