Derby boss Nigel Clough claims his side were denied a "blatant" penalty in the final minutes of their 1-0 defeat at Crystal Palace.

Midfielder Kris Commons appeared to be brought down by Clint Hill but referee Michael Oliver waved away protests and ended any hopes of the Rams claiming a point from the Selhurst Park clash.

Clough - whose side have now lost four games in a row - said: "I thought we created the two best chances of the game and thought we had an absolute blatant penalty in the 92nd minute.

"Anywhere else on the pitch, a late tackle on Kris Commons, and he [the referee] gives a foul.

"When you have seen a player taken off on a stretcher after he's had a shot, I don't think there's any argument that that can be a fair challenge."
