O'Neil is convinced by their attacking options.
He said, "The lads are well prepared and the most important thing between the game in the week and tomorrow was the rest really, making sure the lads' energy levels were back to where they needed to be. Hopefully we've done a good job with that.
“We've got eight days before our next game, so tomorrow's a big one where we can attack it full throttle, give everything we've got, carry the lads off the pitch at the end if we have to and rest them up ready for the trip to West Ham in eight days' time.
“Of course, Nottingham Forest are going to be a tough test. I don't know how they'll react to the big defeat a few days ago. Whether they come and try to shut up shop a bit more than they were. Conceding five goals away from home makes it difficult to know whether they'll come and try the same again or whether they'll be more defensive minding.
“From our point of view, we're trying to remain a threat. The Burnley game was probably our toughest one in terms of trying to create things with the ball because they were very well organised. In general, this season to create as many chances as we have, to keep getting people in key areas, has been a real positive for us."
