A draw appeared the most likely result when Nikola Zigic’s header struck the post, but Marlon King claimed the spoils for Blues with a sublime last-minute volley.
And despite being knocked out of their rhythm temporarily by Dean Marney’s red card, the visitors pleased Clark with the way they killed off their Lancashire opponents at Turf Moor.
The Blues boss told bcfc.com: “I thought the win had gone when Ziggy hit the post. I thought a draw was on the cards but the lads kept going.
“When they went (down) to ten-men, we didn’t adapt to the situation quickly enough because we went with two strikers then – and I changed our formation. They looked as if they got a bit of momentum and seemed a bit inspired by the sending off, but after about five or six minutes our lads done it right. They passed the ball and moved it quickly.
“When you’re a man up it’s not necessary to take too many touches. You play one and two touch, you pass the ball early and crisply, you get it out wide to people who are playing well; like Chris Burke and Nathan Redmond, when he came on. They were causing problems and that’s what we done. I think we controlled the tempo of the game really well at the end of the game.”
King provided the end product for all of Blues’ pressure with the winner, which was his 14th goal of the season in all competitions, and Clark was in the perfect position to admire the striker’s piece of brilliance.
He added: “I think if you look back at the whole goal, it was a deliberate little clipped cross from Wade (Elliott), who I thought was outstanding on his return back here, and there was good awareness from Ziggy. I was right behind Marlon when he hit it and he’s hit it as sweet as a nut. It’s flown in; it’s worthy of winning any game really.”
