Leeds United CEO Shaun Harvey is hoping the club's official complaint to the FA regarding scenes at the end of Tuesday's game at Carlisle will prevent any future scenes of a similar nature.

Harvey confirmed that the club will be contacting the FA regarding an invasion that saw numerous Leeds players accosted by Carlisle fans following the penalty shoot-out at the end of the Johnstone's Paint Trophy tie.

United manager Simon Grayson had spoken of his disappointment at the scenes following the game and the club spoke with both Cumbrian Police and Carlisle United on Wednesday morning.

"Our players found themselves in danger which isn't what you want to see," Harvey told LUTV.

"I have spoken to Simon this morning and on reflection he feels the same way as he did last night - that his players were put at risk.

"We will be contacting the FA to make the complaint, and we have spoken to Carlisle and the Cumbrian Police on the basis that we're going to make the complaint. We will make that and it'll be up to the FA to address that.

"What we hope to achieve is a review of the arrangements that were in place, that ultimately people learn a lesson from what happened, that a group of players are never subject to that again and if any lessons can be learned on a wider scale."

Carlisle's managing director John Nixon said in a statement on Wednesday morning that the situation was dealt with "in text-book fashion."

"It wasn't text-book in our view," said Harvey. "It certainly wasn't the same text-book we would have used.

"They certainly suceeded in keeping the two sets of supporters apart which I firmly believe was the priority for them.

"What they haven't done is protect the safety of our players so if the roles had been reversed I would have stopped short of saying it was a text-book approach, although they are entitled to their view as we are to ours."

Questions have also been raised surrounding the decision to stage the penalty shoot-out in front of a terrace holding fans rather than at the other end where no fans were behind the goal.

"We knew before the game that the penalties would be taken in front of the Carlisle fans because that had been pre-determined by the safety team at Carlisle because they did not feel that it was safe to take them at the other end," added Harvey.

"How someone can justify that it is not safe to take them in front of an open terrace with no supporters is a question I'm glad I don't have to answer."
