Ben Osborn says Nottingham Forest need to show a nasty side to start picking up points after the defeat at Sheffield Wednesday.
The midfielder found the net to pull Forest level at Hillsborough but he said the team need to show more conviction when defending set pieces.
He said: "We started poorly, changed formation and got a foothold in the game. We got the goal and started the second half brightly but conceded from another set piece which is really annoying.
"It is not what we wanted to happen today. It is really frustrating and we need to have a look at the set pieces as it is not acceptable.
"It is a tough place to come; at half time we were confident of going on to win it and it is the small margins in this league. They got the second goal which knocked the wind out of our sail.
"It was good to get a goal; it has been a long time coming but I would prefer to get the result.
"We need to be a bit more nasty and a bit more mature defensively and we will start getting the results. We just need to stay positive and stay confident and start pushing on."
