Gary Caldwell insists Scotland are on course to clinch second spot in their Euro 2012 qualifying group despite the loss against Czech Republic[LNB] Craig Levein's men suffered their first loss of the campaign when Roman Hubnik grabbed the only goal of the game in Prague.[LNB]Next up is the daunting task of facing Spain at Hampden on Tuesday but Caldwell does not believe the events of Friday night have fatally damaged Scotland's chances.[LNB]"We are still on course for finishing second," he said.[LNB]"That was probably always the objective. Spain on Tuesday is a game we will go into and give everything.[LNB]"Everyone in the world wouldn't expect us to get anything and that's when Scotland are usually at their best. So we can have a right go on Tuesday night."[LNB]Levein opted for a controversial defensive formation against the Czechs, with in-form striker Kenny Miller left on the bench until 15 minutes to go.[LNB]But Caldwell defended the ultra-cautious approach, claiming it almost paid off for the Scots.[LNB]He said: "I thought it worked very well. They looked very frustrated, you could see that in their play, and I don't think they had many chances.[LNB]"In the second half, they started to get a few more efforts and Allan McGregor made some good saves.[LNB]"But it was working, it was 0-0 and a point would have been a great result. It was just disappointing to lose from a set-piece."[LNB]Asked if he was surprised when Levein revealed his system to the players, the Wigan player replied: "Not at all. He's got to pick a team that he thinks can get a result.[LNB]"For 70 minutes we were getting the result we wanted and that's his decision. I think it was working.[LNB]"We worked on it all week in training, we watched videos and we understood what we were doing."[LNB]Miller and Chris Iwelumo were both thrown into the action with Scotland trailing and did not have enough time to claw a goal back.[LNB]But Caldwell insists there was no sense of frustration afterwards about not having had a go at the Czechs earlier in the match.[LNB]He said: "I think there is just frustration at the result. We felt we could have got something here and we didn't.[LNB]"That's the only frustration the players and everyone in the dressing room has got."[LNB]Caldwell has yet to play a first-team match for Wigan this season after recovering from two hip operations and he was pleased to last until 15 minutes to go last night.[LNB]"I felt tired as the game wore on but I think that's only natural," he said.[LNB]"But I gave it everything I had and the manager took me off probably after a little bit longer than I thought I would have lasted. I'm quite happy."
