Derby County manager Nigel Clough felt that there was little he could about the penalty given to Coventry City this evening during the Rams 2-0 defeat at the Ricoh Arena.
Speaking to the Press Association after the game, Clough said: "Jason Shackell got the ball. I have not discussed it with the referee because you are not allowed to talk to referees.
"I might get a chance for a word 30 minutes after the game but all you get is a form to fill in and that's it. That's all you can do.
"I thought we created enough chances, especially at the start of the second half. We had a one-on-one but we did not manage to get that goal.
"We have got a local derby with Nottingham Forest next week but performances haven't been much different in the last than they were in earlier games."
