Evans and Woodgate have joined United as part of manager Michael Carrick's staff.
Maguire, speaking to United Review, said of Woodgate: “He was a fantastic player.
“Coaching (here), he’s come in and been refreshing. He brings great energy to the group, to the sessions.
“Obviously he's been a centre-back himself and he’s giving me tips, and he’s going to definitely work a lot with the younger centre-backs, with Leny (Yoro), Ayden (Heaven) and Tyler (Fredricson).
“But, of course, even senior players like myself and Licha (Lisandro Martinez), we can learn from him. He’s brought great ideas and I’ve been really impressed.”
On Evans' return to the club, Maguire continued: “Jonny is great to have around. The way that he handles himself and the responsibility that he took on his shoulders when he was a player, he can take that on to coaching as well.
“Just little things like in the session the other day, I was finished and was walking in and could see that Jonny was doing extra work with Leny and Ayden. Things like that, as a young boy coming through and playing on the biggest stage, sometimes you have to learn and adapt on the pitch and on the stage, but you also can’t forget that you need to improve and you need to work.
“These are young, talented centre-backs and to have Jonathan Woodgate and Jonny Evans coaching them now and giving them little tips, it’s fantastic for them.”
