Arsenal is very sound in their form now and I doubt they are going to allow Nottingham forest deny them of three points in this fixture because for them it counts as they are looking forward to ending the season winning the league title this season. I also believe that there is a chance of draw in this game, such that Arsenal would not want to concede too many goals but Nottingham forest will be mostly doing more of the defence and Arsenal the attack.
We know Arsenal as a team that are always consistent in making the fans go home sad after every game week, now they are the favorite going against a Nottingham Forest side that are not too good for better part of this season but that doesn't mean the Gunners can beat them or put on a better performance with a wonderful scoreline. True a draw can happen in tha encounter and I believe Nottingham Forest will make the Gunners to be confused, meaning that their [Arsenal] style of play won't help them and they can even repeat same weak performance they had against Liverpool. I expect something different and new against Nottingham Forest and they shouldn't come up with that set piece style of play if not Nottingham Forest are ready to defend and hit the Gunners in a counter which I know will be a problem to Arsenal.
