Celtic manager Neil Lennon insists his side will take plenty of positives into Sunday's Old Firm clash at Ibrox despite starting their Europa League Group I campaign with a 2-0 defeat at Atletico Madrid.
The visitors were still warming to their task at the Vicente Calderon when Colombia striker Radamel Falcao met a Diego corner in the third minute to head past Fraser Forster. Diego added the second in the 67th minute to leave the Parkhead men with one away win in Europe in 31 games.
However, the ebullient Hoops boss said: "I don't think there will be any hangover for Sunday's game. The players are relishing it and I am looking for a similar type of performance as Thursday's. I thought we played very well."
He added: "It was a poor start again and we lost a goal from a set-piece but Gary (Hooper) had the chance to equalise and you have to take chances at this level. Hopefully the players will take something from the game for Sunday because there were positives. We will just rest now. I don't think we need to do any training.
"We will make sure we are well rested and will have a recovery session in the morning. But we want to play in these European games and there should be momentum going in to Sunday's game."
Celtic conceded a penalty and a goal in the first minute of their 3-1 play-off defeat in Sion before being reinstated by UEFA, who found the Swiss club guilty of fielding ineligible players in the two games.
Lennon bemoaned the loss of yet another early goal on their European travels. The Northern Irishman said: "It was the manner of the goal. We work very hard on set-pieces and we haven't put a decent challenge in. I felt we could have played higher up the pitch but we did that in the second half.
"The second goal was a killer goal. It was during our best spell in the game, and after that we had to throw caution to the wind."
Atletico boss Gregorio Manzano denied Lennon's claim that the referee Peter Rasmussen had allowed some cynical tackles from Madrid to escape the proper punishment.
He said: "No, the referee let the game flow. I don't think he favoured one team or the other. Celtic kept things tight in the first half but as they tired in the second half we managed to make more of the game. At least one thing people will say is that we have started scoring after two blanks in league games."
