That much was inevitable when the Argentine moved to Old Trafford from Real Madrid for £59.7 million earlier this week, with Louis van Gaal since confirming that he is in line to make his debut at Turf Moor on Saturday.
And training - at least from the looks of it - seems to have gone smoothly, with Di Maria sharing a smile with Juan Mata, David de Gea and more. Even Van Gaal himself was caught smiling, alongside captain Wayne Rooney and Robin van Persie.
In fact, from the looks of things, you wouldn't be able to tell that this was a Man United side under pressure. Make no mistake, however, they are - and they will feel it even more should they fail to attain a result against Sean Dyche's Burnley side.
Only a few days ago, United lost 4-0 to Milton Keynes Dons in the Capital One Cup, while they are yet to win after two Premier League matches this term.
Supporters will hope, though, that the arrival of Di Maria can change all that. Will the Argentine have an instant impact? He certainly looks to have made an impression in training...
