Manchester United manager Sir Alex Ferguson is determined to beat Celtic at Parkhead on Tuesday as he goes in search of top spot in Group F.
United's previously serene progress to the knockout stages of the competition was rocked by their shock defeat at FC Copenhagen in their last group game, and Ferguson is keen to bounce back in style against Gordon Strachan's side.
United play Chelsea in the Premiership on Sunday but Ferguson will be fielding a strong side in Glasgow.
"I haven't made my mind up about who should be left out but they'll be no more than two changes," said Ferguson. "We're well aware of the dangers of taking too many chances.
"The name of the game is to win. There's a marvellous incentive for the players in that a win over Celtic means winning the group.
"You'll get everything on Tuesday night. European games are always special but this is a different type of European game because it will be played in the British spirit.
"It'll be a fantastic match and there will be a great atmosphere. I've experienced the atmosphere at Celtic Park in the past and it's one of the best around. Players can be inspired by that because it creates a great platform for footballers to perform.
"If Celtic were to get themselves in a good position the crowd could help them. But it's important that we work hard to stem the tide of emotion and enthusiasm that can be generated by that support.
"We know we're in for a tough game but we want to come away having won the group."
