The shame of being associated with one of Rangers’ worst ever European away performances extended beyond the 17 players who featured in Jablonec nad Nisou, the coaching staff and the club’s hierarchy.Watching on from afar, Cammy Devlin’s anguish stemmed from being powerless to affect what was slowly unfolding in the Czech Republic.Sent off in the home leg for an ill-advised challenge on Jiri Slama just five minutes after entering the fray, the Australian incurred an automatic suspension.While it might be stretching matters to suggest that one player could have made all the difference last Thursday, the midfielder’s style – busting, energetic and aggressive – was everything Derek McInnes’s side were not as they exited a second European competition of the season.The regret that such a rash decision on his part in the first leg proved so costly is something the 28-year-old will have to live with.’I hate letting my team down and felt that was something I did there,’ he admitted. Cammy Devlin is sent off in the first leg of Rangers’ Conference League play-off The Australian caught his opponent and Rangers went on to lose the tie against Jablonec’I was absolutely devastated. People have seen me play for long enough now, I wear my heart on my sleeve.’So, for that to happen and the way it happened … the still of it looks much worse if you actually watch the moment.’I was so upset for that to happen. I am so desperate to do well.’You have to show resilience in the tough moments and that was another one for me.’There was just no dressing up how poor Rangers were over the two legs. Following the loss on penalties, Andy Halliday said on radio he didn’t know what sport his former club were playing.Even McInnes admitted in the aftermath that he was struggling to discern what the style of play was. Barely a month into the season and the Ibrox club found itself staring at a crisis.’The criticism is deserved – you play for Rangers and got knocked out of Europe,’ Devlin added.’Criticism is part of it. It’s part of playing here and it wasn’t good enough.’The gaffer is so desperate to do well. He’s spoken about that in all his interviews. Everyone knows how much this club means to him.’He played here when he was a young guy. We are so desperate to do well for him, for the club and for the people who support us because it means so much to so many people.’Representing such a special football club, it’s not something you can take lightly.’You have to move on, as hard as it is, you have to look forward and that’s the only way.’Whether last Thursday proved to be the nadir for McInnes and his newly shaped squad, we shall only know in the fullness of time.But after a few days of soul searching, they did show some impressive mettle as they won at Aberdeen on Sunday. Rangers put their European disappointment aside as they beat Aberdeen 1-0 at PittodrieWhile it still required a Lawrence Shankland penalty to get the job done, there was enough energy and desire on show to merit them edging an attritional contest.It certainly felt like the blunt conversations that had taken place in the days after Jablonec had served a purpose.’In the tough moments, if you go into your shell after things like Thursday, you can’t allow that to happen,’ Devlin said.’It’s not easy, you’re so down, but we had come together and had good conversations.’We had a few days in Aberdeen to come together, talk to each other – it was really important and so good to show that camaraderie.’I’ve been in Scotland a while now and that’s what can help the team.’There are so many good players at this club, so many good young players.’But the one thing about playing for Rangers is you don’t get too much time. You have to just throw yourself in.’Sunday was about winning. That was the most important thing. I think we showed a side to us that we maybe haven’t so far.’Any successful team at Rangers over the years, winning trophies, I’m sure it was done by doing the other side of the game too.’It’s not just about playing unreal football, which every team wants to do.’On Sunday, we showed grit and determination, boys doing that extra bit to help their mate.’That’s not the pretty side of the game, but you have to do it and when you watch someone sprinting that extra bit to help their mate, it spurs you on.’It’s something I pride myself on, being the best team-mate you can possibly be.’With Kim Minsu giving the side an infusion of imagination and pace on his eye-catching debut, for the first time since taking charge, McInnes said he enjoyed being Rangers’ manager. Lawrence Shankland’s goal from the penalty spot was enough to win the game for RangersBut it was only one good game in a season which has already seen far more downs than ups.Rangers travel to Falkirk on Wednesday having averted that full-blown crisis yet with a mountain of work to do before it would be safe to say that they are on the right tracks.’The dig and determination to grind out a 1-0 win is as good as they come,’ added Devlin.’It was important to do it. Everyone knows how disappointing Europe was. So, many fans travelled to see that happen.’But we keep our feet on the ground. It’s one win and we look forward to Wednesday now.’We have another tough game. So, we have to keep going.’
