United head coach Buckingham said: “Bolton is a bit of a scar for everybody. We had to make changes, and my job is to try and find ways to perform the way we need to, and get the results we want.
“We made a change after Bolton, and that obviously affected Marcus and a couple of others. He’s been very good behind the scenes and worked extremely hard.
“Because of that, it was about trying to find an opportunity to bring him back because we know the qualities he has.
“He’s shown that, certainly in the first part of the season. With what’s to come, he will certainly contribute towards that.
“It’s important that he keeps doing what he’s done, and I’ve said it many a time, it’s a very close group of people, but you have to be fair and judge the people that have gone in front of him on performance.”
