YORK City manager Russ Wilcox has asked for supporters to avoid any negative chanting during tomorrow's home match with Cambridge.

A chorus of "You're Getting Sacked in the Morning" was directed at the City boss from the David Longhurst Stand following Oxford's second goal 71 minutes into Tuesday night's 2-1 defeat at Bootham Crescent.

The same taunt was repeated at the final whistle but it is the venting of such frustrations during games that Wilcox feels can be counter-productive.

He reasoned: "What I'd say to the supporters is get behind the team in red because they are desperate for that and need it to perform better. It's your team and your football club whether you've been a supporter for two years or 50 but, as each game goes by, every point becomes more important.

"Whether I am manager or somebody else, it's all about what's best for York City and not individuals so, during the 90 minutes, you need supporters to support the team because the negativity on Tuesday doesn't just affect me, it affects the players. After the game, then fair enough - shout what you feel you need to.

"I have no problem with that, even though I'm a human being and nobody likes any form of criticism."

Wilcox is poised to give new on-loan Oxford midfielder Michael Collins his debut against Cambridge and added: "Bringing Michael in is a huge bonus.

"We're not sure how long Luke (Summerfield) will be out but it certainly looks like a few weeks. That's a big blow because he's probably been our best player this season so we needed another good footballer and, hopefully, Michael will fit that bill.

"He's got a good brain for the game and, whilst he doesn't fly around the pitch, Russell Penn and James Berrett can do that. He takes up good positions and keeps possession well, which might help us play more football than we have done in the last couple of games.

"He's also tall and gives us more height in the team. His lack of match fitness could be an issue because he's only been playing development games but he's excited to get this chance and he's an experienced, first-team player. We didn't need a young player because we've already got Ben Godfrey who has done superbly well but, at 17, he needs to come in and out of the team."
