I want no more slip-ups, says Ferguson

Manager Alex Ferguson is demanding no more Champions League slip-ups from his Manchester United team.

A surprise defeat in their last game at FC Copenhagen means United still need a point to be sure of going through to the last 16.

Ferguson wants to clinch their progress in the all-British clash at Celtic tomorrow rather than rely on the final Group F game against Benfica at Old Trafford next month.

"We took a wee risk (with team selection) in Copenhagen and because we lost it didn't work out," he told reporters. "It should have worked out.

"The game in Copenhagen was hard to explain. It was unusual but we are on nine points and we want to make sure we come back from Glasgow qualified."

Ferguson left out Paul Scholes, Rio Ferdinand and Patrice Evra in Copenhagen where he was also without the injured Ryan Giggs and Louis Saha.

Despite a Premier League game looming against champions Chelsea next Sunday, Ferguson will not take any chances with his team selection against Celtic.

Barring injuries, he plans to make no more than a couple of changes to his first-choice lineup.

"There will only be two at the very most, I think, to make sure we qualify," he said.

Celtic lost 3-2 when the sides met in Manchester but are second in the group and know that victory will give them a good chance of becoming the first Scottish team to qualify from the group stages.

Scot Ferguson, who used to play for Celtic's arch-rivals Rangers, knows his players must handle the vibrant atmosphere generated by the home supporters.

He said: "I think it (the crowd) is a definite help to them. I watched the video of their game against Benfica and the support was fantastic.

"We expect that to be a big challenge.

"We have to handle that but we have got players who can.

"We have been in these types of situations before."

"You've got to have players who have the courage to handle the support and the volume of noise," Ferguson concluded.
