The forward has enjoyed a positive first season at Old Trafford and respects Leeds as opponents, not just on Monday night but also in the summer game, that will prove to be an ideal warm-up for the new campaign.
"Obviously, first of all, playing Leeds is a big rivalry for the club," he added. "So it's going to be always good to play these kind of games, especially in this stadium [Croke Park], a big stadium.
"We know we have a big community of fans here and, of course, we're very excited to play in front of them.
"Our one big aim is to be ready for the start of the season, so I think we're just going to try to work as hard as possible to be ready for that."
