However, experienced campaigner Clarke, who made his 300th appearance for the club last Saturday, says they can’t dwell on it as they bid to progress to the last eight of the competition they won last season.
“Last week was very hard to take,” he told the club website.

“We all are very aware that our performance was below par and we got the beating we deserved from Coleraine.
“It is important we put that behind us now for what’s a very important match at Inver Park tomorrow night.”
Clarke though doesn’t think those previous encounters will count for much this time around.
“To be honest, I don’t think it’ll be on our minds too much,” said the full back.
“We all know what the Irish Cup means to everyone inside and outside of the club. We don’t want to give it up after winning it last season.
“The Shield final has no bearing for us as we’ll be treating this as another game.
“We’ll be concentrating on our own game to try and put in a strong performance on the night. Hopefully, we can get a big result.”
It was a busy January for the Blues with five players arriving in the transfer window, and Clarke feels the new additions have give the squad a boost.
“The new lads have all settled in very well and they look to have brought further quality to the squad,” he said.
“I think the new signings coming in definitely gave us all a lift. Competition for places is healthy and they’ll help ensure that’s the case.”
