The 2-1 win saw Birmingham clinch their first Premiership win haing taken just one point from their opening three games.

But Johnson, who hit a stunning winner at St Andrews, insists Blues "have not seen seen anything to frighten the life out of us so far".

He added: "Everyone will take great confidence from winning against a side like that, who will be up near the top of the table.

"We certainly deserved the victory and the lads were ecstatic in the dressing room afterwards.

"It was a crucial win because if you're playing well, which we have been, and then don't get points there is the possibility that heads can drop.

"Now we are off and running and that performance told us we've got a place in this league."

Leeds boss Terry Venables admitted his side had much work to do following the defeat, their second in four days.
