Henning Berg believes Celtic have a tough Champions League task ahead against Manchester United.

The Norwegian won the tournament with former club United in 1999, and he said: "It will be hard for Celtic because of United's form and quality.

"There is also a huge difference in standards from the Premiership to the Scottish Premier League.

"United are big favourites so Celtic need to be compact and well organised to get anything from the game."

Berg moved to Rangers after a spell with Blackburn Rovers.

And he subsequently faced his former United team-mates three seasons ago with the Ibrox club in the Champions League.

But his return turned sour as United ran out 3-0 winners.

Sir Alex Ferguson's team are strong favourites to emerge victorious against the Scottish Champions after four straight Premiership wins.

And the former Norwegian international questions Celtic's chances in the Group F fixture.

"Manchester United play every week against very good teams and Celtic don't have that opportunity.

"It was the same with us when we went down there. I was so looking forward to it but I quickly wanted to forget it," he said.

"At Rangers, we were used to playing in the SPL and Celtic and Rangers are expected to dominate all the games.

"But the opposition this week is so much better so Celtic have to stick together and defend well as a team.

"However, you can't say they don't have a chance because of the quality and Champions League experience they have," he added.

Gordon Strachan's side will have to stop in-form Ryan Giggs and returning duo Wayne Rooney and Paul Scholes, according to Berg.

"Ryan Giggs is one of the very best players in the world, no doubt about it.

"Wayne is capable of making things happen if they were tight and Paul's awareness is incredible," he added.

"They might not be 100% match fit but those two don't need games - they will be on fire for this one."
