Celtic will travel to Denmark in a tough encounter with the battling Danes who managed to nick a point in their previous encounter in Glasgow. It will be a match of great importance for the Scottish side, who need as many points as possible to guarantee their survival in the European tournaments this season, be it the Champions League or, more likely, the Uefa Cup.

Celtic will be boosted by some good news, with midfielder Aiden McGeady declared fit to play prior to the clash with Aalborg, having recovered from calf and knee problems to travel to Denmark, although he is not definite to figure in the starting 11. Manager Gordon Strachan has announced on the official Celtic website that a final decision will be taken on his participation after training with the team.

Another long-term absentee, striker Jan Vennegoor of Hesselink, who has not played for Celtic since injuring his groin against Hamilton last month, is also included in Strachan's squad, and he too awaits final evaluation from the Celtic medical team before the match.

Massimo Donati is definitely out of the picture with a broken toe, but fellow midfielder Paul Hartley's ankle knock has improved, and there might be a possibility for him to play at a later stages. He picked up the injury whilst playing on Scotland duty but was considered fit enough to take a place among the substitutes at St Mirren at the weekend and as apparently there has been no inflammation or deterioration of his condition, he has a good chance of being deployed on the pitch.

"It is a must-win game for us," said former Celtic skipper Neil Lennon. "I think it will be a British style game as the Danes are physical and hoof the ball a lot. We are in good form and we want to get that monkey off our back in terms of winning away from home. We have plenty of attacking options and players capable of scoring a goal at any time. It is frustrating that qualifying is out of our hands but we have to get on and win this game and that is not a certainty by any means," Lennon said, as quoted by the Celtic website.

Aalborg meanwhile are in lethal form, having presided over an eight-match unbeaten run since the appointment of a new manager last month. Allan Kuhn had the confidence to declare on the eve of the clash with the Scottish champions that his players would definitely score when they face Celtic.

"Celtic are a strong team but they do concede goals," said the 40-year-old. "I feel sure we will score against them and, if we play like we did against Villarreal, then we have a good chance of winning. It is always important to score the first goal and if you do that in the Champions League, it gives the players a lot of confidence. That will be important on Tuesday because it's a really big match for both teams," Kuhn said, as quoted by the Uefa website.

After the previous Aalborg manager, Bruce Rioch, was replaced by Kuhn, the Danish champions have not been defeated once, going on a run of four victories and four draws, a sequence which pushed the team to seventh in the Danish Superligaen, whilst also ensuring progress to the Danish Cup semi-finals. The team also displayed a great battling spirit after having  twice come from behind to secure a 2-2 draw at home to Villarreal in their last match in the Champions League.
