Cahill hopes a winning trip to the Far East can get the Blues back on track.
He said: “It’s going to be a good competition for us. Hopefully we will come back flying. I don’t know what’s gone wrong. That’s the honest answer. It’s the same group of players.
“The players have been asking that question themselves and we don’t know really.
“Where do you point the finger? It’s obviously stuff you need to work on in the training ground.
“It’s the same group of players who started the season beating teams and scoring goals and keeping clean sheets.
“There’s no reason why we can’t get back to that, but we were hoping it would come sooner.”
