Russell Martin cautioned his Rangers team that they need to significantly enhance their performance following Tuesday night’s match in the Czech Republic if they are to retain the £40million prize for qualifying for the Champions League.

Despite a 2-1 defeat in the second leg against Viktoria Plzen, the Ibrox team advanced to the play-off round, with Martin expressing his frustration over certain aspects of their game.

After a commanding win in Glasgow last week, his new-look side prevailed 4-2 on aggregate. 

‘I’m disappointed we lost and I am disappointed with how many chances we gave up,’ said the Rangers head coach. ‘I think much of it stems from being careless with the ball.

‘We were playing against a team who had nothing to lose, who really committed so many numbers, four on the top line, with a heavy press.

‘We often played through the press in the first half and reached their final third frequently, only to give away possession. From our perspective, it was self-inflicted.

‘I told the attackers: “It’s not fair on our defenders to deal with such intense pressure, Jack (Butland) is finding you, yet you yield possession so easily”.

‘I don’t mind you losing the ball if you’re so aggressive, one v one, taking someone on, but the lack of care on the ball was too much.

‘We conceded a goal, and then we improved after the break and we scored, and then the level of intensity dropped.

‘It was like: “Okay, job’s done, we can relax”. You can never relax playing against anyone, especially for this football club. 

‘So, again, another brilliant bit of learning and we’re through to the last qualifying round, but I am annoyed. 

‘It’s my responsibility to be critical of certain things, yet we will also highlight the positives. However, our overall execution wasn’t sufficient. There were too many tense moments for the opposition that we should have managed better.’

Pressed on whether his team need to step it up against Club Brugge, who made it through to the play-off with a 4-2 aggregate win over RB Salzburg, Martin replied: ‘If we don’t show a bit more care and quality on the ball, I think we will struggle against anyone.

‘I don’t feel relieved, I’m just a little bit annoyed that we’ve lost, a bit disappointed with some of the bits of the performance.

‘When we do show care and quality on the ball, we look fantastic at times. But the gap between us being good with the ball and not being good is too big. That will come.

‘Brugge are a good team and it will be a tough game. We play at home first and we know that can be really powerful for us, so I’m excited.

‘We know the levels will go up at this stage of the competition, but we’re excited about it.

‘Jack (Butland) and the two centre-halves have been brilliant for us. They are the ones who have really had to take on so much information.

‘If everyone can match their level of intensity and mentality, we’ll be fine.’

Rangers fell behind to a first-half goal from Plzen striker Durosinmi, before Cameron scored shortly after the break.

That should have settled any nerves but this became a night fraught with nerves for Rangers as the home side spurned several good chances.

Plzen eventually scored a second through Markovic, but it wasn’t enough to overturn the deficit.

There was concern in the second half when Cyriel Dessers went off with an injury and Martin confirmed the initial prognosis did not look great for the striker.

‘Yeah, it looks a nasty one, so he’s in a brace now,’ said the manager. ‘We’ll have to just wait and see over the next couple of days, have a scan and see.

‘We’ll keep our fingers crossed it’s not too bad for a big man.’

Meanwhile, it was announced that Rangers have withdrawn their request to postpone their Premiership clash with St Mirren in Paisley, which takes place between both legs of the play-off with Brugge. 

The match will take place as planned on Sunday, August 24, with a midday kick-off and live coverage on Sky Sports.
