United take on Palace at Old Trafford tomorrow (3pm) with Louis van Gaal's side looking to end a three-game winless streak.
And Di Maria is set for a starring role having impressed following his British record £60million summer switch from Real Madrid.
But the Argentina international's pre-weekend shopping basket suggested he was getting ready for a party rather than Palace.
Di Maria, 26, popped in to Waitrose earlier this week with wife Jorgelina, 32.

The husband and wife visited the supermarket in Alderley Edge, Chesire, to pick up some supplies.
But unlike Daniel Sturridge who picked up bagfulls of healthy foods on a recent shopping trip, it seems Di Maria has more of a sweet tooth.
The World Cup star was spotted next to a trolley brimming with fizzy drinks and beer!
Dressed in a grey jumper, jeans and white trainers, Di Maria is seen carrying bottles of water, whilst a friend pushes his cart.
The winger's trolley is stuffed with multipacks of Sprite, Fanta Lemon, Fanta Orange and bumper packs of caffeine free Diet Coke and Coke Cola.
Also in the mix is a crate of Corona!
Maybe Di Maria is getting the beers in early in anticipation of three points tomorrow...
