Then Niall McDernott's free just makes it over the bar to put Cavan three points to the good.

"I have no doubt the hairdryer will be out in the Monaghan dressing-room at half-time. Monaghan didn't look up for it in the first five minutes and it is very hard to lift it when you don't come out with the right attitude."

"Cavan are the more hungry team and they are getting more turnovers. Monaghan need to try and hit more long-range points in the second half."
