Jones has started nine of United's 13 matches so far this season and has impressed recently when stepping into his favoured centre-back position.
"He's certainly got it in him to be a regular starter and he has played well so far this season," McGuinness told ManUtd.com. "However, one thing is important and that is not to expect too much from him. It's easy to forget that he's still a young lad and is still improving as a player.
Jones' powerful style of play and professional performances have, in the past, drawn comparisons with a certain Duncan Edwards - most notably from Edwards' team-mate and United legend Sir Bobby Charlton.
"For me, because I think so highly of him, you can't compare anyone to Duncan Edwards. But Phil is a similar age to Duncan when he started to play for United and, like Duncan, he has been able to forge a way into the first team despite being so young."
