“It’s one of those defeats where you can’t really analyse what went wrong from our point of view.
“We were very unfortunate to get knocked out of the cup like that but now we have to move on from that.”
Allen believes Liverpool made another statement of intent in the way they dominated the tie in London.
“We created some great chances which was a positive to take from the game,” Allen continued.
“Our league form was very good before the cup game and we’ve got to get back to that. We’ve got 12 big leagues games to go and there is everything still to play for this season.”
