Cardiff manager Erol Bulut was delighted with his team’s 3-1 victory over Birmingham – and hopes he can bolster his defence before Friday’s transfer deadline.

The Bluebirds boss watched as his side scored through Rubin Colwill, Ryan Wintle and Zion Etete and saw Blues’ Lukas Jutkiewicz sent off midway through the second half.

They did so having made 10 changes to the side which beat Sheffield Wednesday at the weekend – and with a makeshift defence as Ebou Adams lined up alongside Perry Ng and full-back Mahlon Romeo.

“I am delighted because today we played without centre-backs, we created a back three with midfielders,” said Bulut.

“After the opponent was with 10 players we get a little bit relaxed and thought the game was finished. It is not finished, sometimes against 10 players it is more difficult.

“We need centre-backs, today we tried to create centre-backs. I hope at least one, maybe two centre-backs.

“I cannot see anything, wait until Friday then we will see some surprises – I hope.”

Blues counterpart John Eustace felt Jutkiewicz’s dismissal was the turning point.

“I thought it was very harsh from where I was, Jukey was pushed over at the start, he was rolling over then he has turned to try and get the ball and he has caught the lad on the back of the legs,” he said.

“It is a hard red card, it is something we will have to look at and see if we can appeal it. I will have to have a good look again tonight.

“I felt the first 20 minutes caused us a lot of problems, their shape, we couldn’t get used to that. The early goal certainly helps them as well.

“I thought we grew into the game, we got to grips with their shape, we were better with their press, were higher up the pitch. We need to be better in that final third with the decision-making.

“Coming into half-time we were positive, we tweaked a couple of things and I thought we started the second half quite well then obviously the red card just changes the game.”
