Kanchelskis, speaking exclusively to AmericanGambler.com, said of Maguire: "I don't know. He's not someone that inspires you like a Roy Keane. He's a little bit quiet and doesn't really sparkle. You look at how Roy Keane and Bryan Robson used to fight on the pitch, he's a little bit quiet and needs some determination and be a bit more aggressive. This is football; it's not ballet."
The Russian also insists Ole Gunnar Solskjaer is the right man in charge.
He added: "My opinion is that United are better keeping Solskjaer at least until the end of the season, and see what happens. Why change manager halfway through the season? It would just cause big problems. It's a decision for the chairman if he wants (Mauricio) Pochettino, right now United are going okay, they're doing well in the Champions League, and the performances are getting better in the league. Look at Man City. They started badly and people are saying get rid of (Pep) Guardiola. It's crazy. You need time."
