POLISH striker Maciej Zurawski rates the experience of humbling mighty Manchester United as one of the highlights of his career.

And he reckons that shock result at Parkhead two years ago proves anything is possible when Celtic are playing in front of their own supporters.

Zurawski was part of the Hoops side which stunned the Premiership giants by defeating them 1-0 in a Champions League group clash two years ago, sending shockwaves around European football as they sealed a place in the last 16 of the competition.

As coupon busters go, it was right up there with the best of them. Shunsuke Nakamura's wonder free-kick inflicted a defeat on the team that was widely expected to go on and win the tournament.

The result didn't go down well with their Scottish manager Sir Alex Ferguson.

Perhaps that was partly responsible for the thrashing the English champions dished out to Strachan's men a couple of week ago at Old Trafford, when a Dimitar Berbatov double and a Wayne Rooney strike handed the European champions a comprehensive 3-0 victory.

Zurawski, however, believes the magical atmosphere that is generated within Celtic Park on European nights.

And with United coming to Parkhead next week looking to avenge the 2006 defeat, Magic has offered some words of encouragement to his former team-mates.

"There is something very special about the atmosphere at Celtic Park on European nights," said Zurawski. "From the second you walk out the tunnel for the warm-up you can sense a special feeling in the air.

"I had friends over from Poland for some of the European matches and they couldn't believe how loud the crowd were. The fans really, really got behind each and every one of the players and sang their hearts out for the full 90 minutes.

"I think the Celtic supporters really like to get behind their team on those nights and it certainly tends to bring out the best in the players. When you have that sort of backing you can't help but be inspired by it all.

"When you look at some of the teams who have come to Parkhead in the past, some during my time at Celtic and some in the few years before I arrived, then it only goes show you that anything can happen on the night.

"If Celtic play well enough, and with such a passionate crowd behind them, then you must feel like you always have a chance of picking up a good result. I would never write Celtic off when they are playing at home."

Zurawski still recalls his side's success over Manchester United and believes they were well worth their win that night.

"Manchester United were a world-class side a couple of years ago," he said. "They still had the likes of Wayne Rooney, Ronaldo, Ryan Giggs and Rio Ferdinand. They were an outstanding team and I don't think anyone really expected us to win the game.

"Our mindset was to keep things tight and prevent them from scoring early in the game. We knew the longer the scoreline remained 0-0, the more frustrated they would become and the more we would grow in confidence.

"Once we managed to do that I thought we settled into the game quite well and performed pretty good. We knew our best chance of scoring would probably be from a set-piece, such as a corner or a free-kick - and with Naka then you always have a chance.

"Maybe Manchester United, for whatever reason, didn't appreciate just how good he at hitting free-kicks but it was an excellent effort. But it seemed to take an eternity to find the back of the net.

"I was on the bench during the second half as Shaun Maloney came on for me but the celebrations were fantastic and it was a great night for everyone involved."

Zurawski concedes United have improved in the last couple of years and admits their display in their recent 3-0 win over Celtic confirmed as much.

The striker, who plays for Greek side Larissa now, explained: "When we went to Old Trafford we managed to complete with them even although they beat us 3-2. But obviously they won by a few goals in the last meeting.

"You see United doing that to teams in England. If they click on the day then there isn't a lot you can do about it unfortunately.

"But Celtic have got to be positive next week and believe they can do it. The fans will get right behind them and you just never know."
