JACK Cork has urged Burnley to get Monday night’s FA Cup disappointment out of their system at the first attempt with a derby double.

The Clarets went into their fifth round tie at West Ham United having progressed to within two places and six points of the Championship top six, with two games in hand as their cup exploits resulted in a double postponement.

Four points from the 11 earned under new boss Eddie Howe came from their last two fixtures – both away – they will look to pick up where they left off by taking maximum points from relegation threatened Preston North End on Saturday, and not dwell on crashing out of the cup 5-1.

“It is disappointing when you get knocked out of the FA Cup, considering you are three games away from the final and two games away from Wembley,” said on-loan Chelsea midfielder Cork.

“There’s no excuse because we could have done better for all the goals.

"There’s no one person to blame and now we have to get ourselves ready for the league game on Saturday.

“Our aim at the end of it (this season) is to try and get to the play-offs and try and get promoted so we have to forget about this as soon as we can.”

But Cork admitted he was stunned to have been involved in two such contrasting halves.

The Clarets felt unfortunate to go into the break a goal down at Upton Park after outpassing their Premier League hosts in the first half.

But two Carlton Cole strikes in the first five second-half minutes ultimately killed off any challenge.

“We felt like we played really well in the first half so it was very disappointing in the second half,” said Cork.

“We came in 1-0 at half-time disappointed because we played some really good stuff and created a few chances. Chris Eagles had a couple and Jay (Rodriguez) had a couple.

“I really enjoyed it in the first half and the way I felt afterwards compared to the way I was at half-time was completely different.

“The three early goals killed us and everyone came in really disappointed because after that we played really poorly. There were no excuses really.”

But Cork urged the Clarets to focus on the bigger picture and keep working towards an immediate Premier League return, starting with completing a Lancashire double over their bottom placed rivals.

“Preston is a big game. In the last game we played them they showed what they can do and they can score goals.

"We were 3-1 down and we won’t want to be in that situation again,” he warned.

“Our ultimate aim is to try and get out of this league so we have to get (the cup) out of our minds and try to get up.”
