Rangers booked a Champions League play-off against Club Brugge but manager Russell Martin was “annoyed” at “too many scary moments” in a 2-1 defeat at Viktoria Plzen.
Rangers won through 4-2 on aggregate after a first-leg win last week but were made to work away from home once again.
They fell behind on the night when Rafiu Durosinmi scored but Lyall Cameron levelled on the hour with his first Rangers goal.
Plzen substitute Svetozar Markovic restored the home side’s lead in the 83rd minute when he took advantage of more sloppy marking and the Light Blues could have conceded more, with goalkeeper Jack Butland again in fine form.
Martin has voiced his complaints about his players already this season and said: “I’m disappointed we lost. We had some really good moments, but disappointed how many shots we gave them, how many chances we gave them.
“And also disappointed with how many times we got in and around their box, with overload, big numbers, and then don’t execute the final pass.
“So there were some really good moments of football. We saw the game out really well in the last seven minutes with some really good football.
“But there were way too many moments for them, that were self-inflicted as well, really.
“We have to be really relentless. So I’m disappointed with the performance, I’m disappointed with the result, but there’s lots to build on, and we just need to be cleaner with the ball.
“We’re through to the last qualifying round for the Champions League, but I am annoyed.
“It’s my job to be annoyed at some of the stuff, and also, we’ll show them some of the really good stuff as well.
“But that wasn’t enough. There’s too many scary moments for the opposition that really we can do better with.”
