Coventry City manager Mark Robins was not happy with having another goal chalked off.
After David McGoldrick's goal was ruled out last Saturday, today Richard Wood had a goal ruled out which would have made it 3-0 to City.
Speaking to the Press Association, the City boss said: "The disappointment for me was that we had a goal chalked off again that was perfectly good.
"It's the second time in two games at home, and if we had that it would have killed the game. But as usual we fail to do something that gives them an opportunity.
"It's about defensive responsibility and getting into position quicker than we did do because we ambled back in. Those are the things that teams that win things do well and consistently, and that's the negative.
"The positives are that we have lost two or three players for this game and two or three came in and gave a good account of themselves."
Robins added: "Initially we struggled to get on the ball and play the game we wanted to because they were keeping possession so well until we tweaked it slightly and got into the ascendancy and played some decent football.
"I thought some of the football was excellent from both sides, us particularly, but I still want more."
