Walker was assistant boss under McEwan for two years before the Scot's departure last season and the two now clash swords as McEwan's second-placed Stags visit Kit-Kat Crescent.

All the focus will be on the managerial head-to-head but Walker is focusing first and foremost on three points for his unbeaten Minstermen.
"The main issue is about us getting back to winning ways," said Walker, whose side drew 1-1 at Torquay on Thursday.

"He is doing a fantastic job for Mansfield – the same as he did for York and I wish him well against every other club and in every other match apart from this one."

Walker also feels McEwan will get a decent reception on his return and admitted he gained valuable experience form his former employer.

"I don't think the fans had a proper chance to say goodbye to him and I think he will get a good reception," said Walker.

"Our relationship was a football one but I learnt a lot from him that I have taken forward into what I am doing now."
