Cardiff City boss Neil Harris feels his side will have to overcome Nottingham Forest's defensive stability if they are to get a result this weekend.
The two sides meet this weekend at the City Ground, with the former Forest striker looking to maintain his unbeaten start in the Bluebirds dugout.
Forest have conceded only 13 goals this season, second only to Leeds United in the Championship and Harris thinks that is the main thing that Sabri Lamouchi has implemented.

“What Forest have added this year is the defensive mindset. They’ve been searching for that and they’ve done well defensively," he told WalesOnline.
“They look like a good, all-round team. I know some players quite well, Lewis Grabban for example, I played with at Millwall a while ago.
“We have to make sure we deal with their threats as we did against Stoke. We have to find ways of hurting them and that’s where teams have struggled.
“They can play quite deep and narrow.”
Harris spent two season with Forest during his playing days, arriving after a spell with the Welsh side. However, it's not a time he looks back fondly on. Earlier this season, Harris recounted that time on the Trent as the main disappointment in his career.
"I went to Forest, I should have stayed at Cardiff really. That was probably the real disappointment in my career."
