Jon Dahl Tomasson says Rovers must work to eliminate their mistakes after being denied victory in the final minute of their FA Cup fourth round tie with Birmingham City.

The sides will have to do it all again on Tuesday night at St Andrew’s after Jordan James scored a 90th minute equaliser.

Rovers were also punished after three minutes, as Reda Khadra’s shot beat Thomas Kaminski after Tyler Morton had given the ball away.

Inbetween, goals from Bradley Dack and Joe Rankin-Costello looked to have sent Rovers into round five

An improved second half display saw them create a number of good chances to make the game safe, only for Blues to pounce in the dying stages.

The equaliser came about after Scott Wharton failed to cut out a ball down the channel, while Kaminski was unable to keep out James’ scuffed shot, despite getting a hand to it.

Football is about mistakes on and off the ball, and of course we should try not to make those mistakes because it costs us a lot and we were in a great position to win the game and we should probably have won it,” Tomasson said.

“We're disappointed but on the other hand, coming back from conceding an early goal the way we did, the way we played football and created chances was positive but we should have killed the game and managed those opportunities.

“That's football, hey. In this situation it is annoying but that's football, it's about passion, things can go wrong.

“It happens and that makes the game so interesting. Today we are extremely disappointed with it, and we need to deal with it.”

Dack scored just after the half hour mark to level things up after Khadra’s early strike.

Rankin-Costello netted just a minute into the second half, with Ben Brereton going close to a third during Rovers’ best spell of the match.

And Tomasson added: Yes, of course I'm disappointed to not win the game if you look at the situation we were in.

“I think Birmingham has a good side but of course, their recent form has not been that good.

“I think the team did well to come back from that early goal, and it put us in a great position to win the game but we should manage the game better, kill the game with those opportunities.

“We played some good football when we first scored, but of course in the end, conceding a goal and making those mistakes, we need to take that out of our game.

“On the other hand, we're still in the draw and we will go to Birmingham on Tuesday and try to win the game.”

The quick turnaround means the replay will clash with transfer deadline day.

Asked if that will interfere with their plans, Tomasson said: No, hopefully we should have all our players in for that. We should never waste a window, we want to become better in the right direction. It's a little bit out of my hand.

“I know people are working hard on it to solve it in a difficult January window, but of course we should always try to become better with either short-term or long-term signings depending on the options.”
