Hughton admitted Martins had been unhappy to be replaced by Viduka with 25 minutes remaining after he had made that gesture then headed straight down the tunnel.

"On the back of last week, what we wanted to do was keep a clean sheet.

"On the back of last week, what we wanted to do was keep a clean sheet.
"We felt we had enough in the team to score us a goal here, and as the game opened up in the second half, I genuinely feel, although it could have gone either way, we got into the better areas and if our final ball had been a little bit better, we could have gone on and taken the three points.
