The Gers secured progress to the semi-final with a 1-0 win over Livingston.
Mark Warburton’s men have had to grind out results in recent weeks and it proved to be the case again when Livi arrived at Ibrox.
Mark Burchill’s team were dogged and determined, and kept Rangers at bay until Clark’s 75th minute strike edged the Gers ahead and into the semi-final of the Petrofac Cup.
“We kept at the task, they were tough to break down and we had to be patient and we kept moving the football and got in good areas,” he told Rangers.co.uk.
“We were not quite as clinical as we needed to be at times but we got the result and we’re into the semi-final.
“I hope the fans saw the character because it was a show in spirit for everyone, not just the players but the fans as well.”
Rangers’ blistering start to the season has increased the fear factor around facing them and as a result, opposition teams now set up not to concede rather than to take the game to the Ibrox club.
Breaking down any team with ten men behind the ball is a tough task and the Gers have had to be patient in sticking to their possession-based football in the last few encounters.
The temptation to lump balls into the box must be there but Warburton’s commitment to his footballing philosophy has prevented that, and Clark wants the Gers’ faithful to support that approach.
“You heard the fans reaction and the supporters were really strong tonight but we have to stick with the game plan and the more we can learn to break teams down the better we will be.”
