Now firmly established with the Foxes - he was their Player of the Year last season - Drinkwater is determined not to be overawed by the occasion.
"I'll have to take it in my stride," he told MUTV. "If you get fazed, it only has a negative effect. So I'll be getting on with my game and not concentrating on the big names. Louis van Gaal has changed an awful lot there - and for the better it would seem from last weekend. It's exciting as a fan.
"I suppose Sunday's going to be a bit mad for me being a United fan but I'm looking forward to it. Hopefully, my family will be supporting Leicester because of me but they're United fans as well. I like the Reds to win wherever they go but not this time!"
The Foxes have a sizeable contingent of former Reds in their squad - Danny Simpson and Tom Lawrence are the latest to arrive, linking up with Drinkwater, Ritchie De Laet and Matty James. Nick Powell is there on loan and all of them are looking to help Leicester consolidate their position in the top flight after coming up as champions.
"It's great, and it's made it easy for them [the ex-United players] to settle in," Drinkwater added. "There's a good balance in our squad and we're all excited about the challenges this season. We've had a few tough games so far but we've more than put ourselves about. It's about keeping that going and staying on track."
