Robin van Persie was substituted as a precaution after being chosen to lead the line while Danny Welbeck also pulled up sharply after challenging for one through ball but soldiered on. Meanwhile, Rio Ferdinand and Michael Carrick were left on the sidelines for the entertaining clash.
"We've got a couple of wee worries," explained Moyes to MUTV. "Robin just felt his thigh in the first half and we didn't want to take any chances.
"Danny Welbeck felt his groin when he came on and we've just got to make sure they're all okay especially with so many games coming up. We've still got a few games to play before the season starts when we get back home."
Chris Smalling and Ashley Young enjoyed run-outs as they step up their bid for full fitness while Wayne Rooney remains on course to feature later in the pre-season campaign.
"With Rio, we just decided to give him a rest. I wanted to get Jonny Evans and Chris Smalling a game so we rested Rio. Michael just felt his groin. It's a bit tight from last night. It's not anything we can see keeping him out. He just missed training and the game tonight.
"As far as we know Wayne [Rooney] is coming on, He's started light jogging and the feedback I'm getting from the physios is that he's progressing. Hopefully those dates are still on track."
