Nottingham Forest manager Mark Warburton joined the Reds in March after leaving Rangers in February
Manager Mark Warburton believes Nottingham Forest need to be more intelligent against the physical sides in the Championship.
The Reds were beaten 2-0 by Cardiff on Sunday to remain ninth in the table.
Warburton told BBC Radio Nottingham: "We knew the threat from Cardiff. They are physical and are a very good team.
"I don't think we were bullied but our job is to move the ball better, be more penetrating and have more guile in that final third."
The defeat ended Forest's four-game winning streak at home and they remain five points adrift of the play-offs.
"It was frustrating. I have to be careful what I say but for their first goal surely it was a foul on Tyler Walker," Warburton said.
"The second goal was a long punt from when we had possession, so a very poor goal to give away.
"In between, there was a really good chance we did not take and likewise in the second half at 2-0 there was another chance we did not take.
"They are the fine margins. We did not take them at Birmingham, we took it against Norwich and that's the nature of the game."
