Six-foot four in his stocking soles, blessed with pace and physicality, there’s plenty which points towards Manny Fernandez being a top defender.Unfortunately, from Rangers’ perspective, it’s becoming clear that there’s one key part of the jigsaw which is presently missing. His attitude.At Tannadice last Friday, he didn’t look to have a care in the world when sauntering back up the field as Dundee United scored a goal which ultimately cost Derek McInnes’s side two points.Any supporter who believed he’d have learned a harsh lesson on that opening night will have been forced to think again after another unconvincing display in Poland.Twice in eight minutes, he got it all wrong again as McInnes saw a one-goal lead turn into a one-goal deficit and his side enter the danger zone in this Europa League qualifier.The player’s attempt to readjust his feet and deal with a routine low cross was dismal. One can only imagine that the own goal he chalked up consequently was still running through his head when he slipped while trying to defend a cross from the other flank just before the Poles struck again. Rangers players appear to be in shellshock as they see their lead very quickly turn into a deficitTo think that back in April the player was being linked with a potential move to Arsenal or West Ham…At the weekend, former Ibrox midfielder Andy Halliday spoke of individuals presently at the club who didn’t seem to want to defend. He didn’t name names, but he didn’t have to.At the age of 24, Fernandez doesn’t seem to have realised that showing the right commitment and mindset for 90-plus minutes are non-negotiable. McInnes already must be tired of telling him.He was not alone in producing an error-strewn display. Having looked capable of being – in his words – ‘the man’ this season on Tayside, Thelo Aasgaard regressed to the player of last term. It was his cheap concession which allowed the Poles to claim the second.Neither Dan Neil nor Tochi Chukwuani imposed themselves on the contest enough to merit a start in next week’s return leg.The main positive for McInnes came in the shape of the display from the bench from Findlay Curtis. How the manager could have done with more of his charges showing the kind of courage the teenager exhibited.The return of Nico Raskin at the break also elevated those around him. But an improved second half display will have come as little consolation to those supporters who made the long trip. Kacper Szmyt celebrates after putting the home side ahead in the Europa League qualifierThe Poles were competent, yet no greater than that. With another league game against Hibs to come at the weekend, Rangers should have enough to turn the tie around. If they don’t, there will be severe recriminations.There were only 1,027 Rangers fans inside the Chorten Arena in north-east Poland for what they’d hope to be the first of many foreign adventures this season.Having made plain his concern over the way his side performed at Tannadice, McInnes shook things up with five changes. There was a debut for Daisuke Yokota following the winger’s move from Hannover. Ross McCrorie effectively replaced the injured Ben Godfrey, Neil and Chukwuani were brought into midfield with Youssef Chermiti tasked with leading the line.There was a familiar face in Jagiellonia’s line-up. Yuki Kobayashi only managed a handful of appearances in his two years with Celtic, but his weak display in a 3-0 loss at Ibrox in a dead rubber three years ago pretty much sealed his exit. Yet the Japanese was terrific here.McInnes had identified that the Poles set up with a narrow formation. The onus was on his wide players to manipulate the space on the flanks and ask questions. Inside four minutes, Tuur Rommens and Mohamed Diomande did exactly as he would have demanded.It was a brilliant exchange between the pair to open the game up. Rommens fed the midfielder then bounded forward to receive an incisive pass. The Belgian’s cross had pace and direction and caught Guilherme Montoia in a state of panic. For reasons only he could explain, the Portuguese fired the ball into his own net.Having won possession back, Chermiti threatened to find a second until Slawomir Abramowicz got a hand in the way of his strike. But the bright start from the Scots just did not last. They dropped off the game and made elementary errors. Rangers new boy Yokota helps Rommens celebrate his role in the own-goal openerYokota didn’t do nearly enough to stop Kajetan Szmyt pulling the ball back onto his right foot and crossing. All that was required was some assertive defending. Instead, Fernandez had another moment to forget.Stretching for the ball when he should have sent it back where it had come from, his studs steered it onto the target. Ivor Pandur could only watch on in horror as it crept inside his post. And with that, Rangers lost their shape.Coming on 21 minutes, the Poles’ second was another horror show from McInnes point of view.Maybe Aasgaard had read too much of the praise which has been since lavished on him post-Tannadice. An unnecessary flick in a promising position turned the ball over and the home side were on their way.Down the right-side Nik Prelec went, his run and cross going unchecked. His cross demanded concentration from those in blue but Fernandez lost his footing at the key moment.It allowed the ball to run through to Jesus Imaz. Pandur got an outstretched hand to the first effort but was a beaten man as Szmyt thumped home the rebound. This one belonged to him.The hydration break gave McInnes a chance to exchange some words with his players. They wouldn’t have been complimentary. Rangers manager Derek McInnes tries to get his message across during a hydration breakAnother surge from the home side saw Fernandez fail to deal with the situation. This time, Rodrigo Conceicao smashed the ball into the side netting.Notwithstanding an excellent tackle by Kobayashi to deny Chukwuani, it was all Jagiellonia until the break. Prelec’s deflected shot was beaten away by Pandur. The Croatian also stopped Norbert Wojtuszek’s strike.Raskin, Cammy Devlin and Findlay Curtis were thrown on for Neil, Chukwuani and Yokota at the break. It became more encouraging.Devlin’s tenacity on the hour mark presented Aasgaard with a chance to level. The Norwegian’s shot was wayward. Curtis was inches away from turning Raskin’s cross home before Devlin’s shot was tipped over.For all that, a Rommens’s error led to Imaz steering a cross past the post.Curtis was bright down the left, a string of crosses begging to be dispatched. McCrorie saw a shot deflected wide by Kobayashi after Curtis’s initial shot had been tipped away.It wasn’t to be Curtis’s night, though. Deep in injury time, he saw a volley come straight off the post. He deserved more. Rangers did not.JAGIELLONIA BIALYSTOK (4-3-3): Abramowicz 6.5; Wojtuszek 7, Konstantopoulos 7, KOBAYASHI 8, Guilherme 6.5; Rodrigo Conceicao 6 (Agbonifo 65), Romanczuk 7, Lozano 6.5 (Klynge 65); Szmyt 7, Prelec 7 (Sylla 80), Imaz 6.5 (Drachal 80).
