Evans has been sidelined with a foot problem but returned in the Under-21s' victory against Aston Villa on Monday and travelled with the squad to Bayern Munich for the Champions League quarter-final second leg.
McCreery believes the final five games will provide the centre-back with the perfect opportunity to show manager David Moyes that he should be a regular choice next term.
"Jonny will definitely be in that defence for a long time, and especially for Northern Ireland as well, it's just that he has had a few injuries," McCreery told ManUtd.com.
"Unfortunately, if you look at it, these have come at an important time as well. Saying that, Jonny has had experience and is not a young lad anymore.
"He's gained that experience by playing at a young age at United and experienced winning things too. I think United could do with him coming back as quickly as possible.
"With Nemanja Vidic leaving, the club needs a good balanced partnership to start next season. Jonny can be part of that and he's got leadership qualities. He's the type of lad who you think is quiet off the pitch but, once he gets on the field, he changes. And he's a lovely lad."
