Arsenal must stay winning to increase their chances of catching up to Liverpool, while the gap is a lot, the reds doesn't appear weak. However, it's clear that Fulham may lose the match, but betting on their Victory is tempting. On the other hand, Nottingham forest and Man U does seem to have an equal strength, a draw is close, yet winning is possible for both teams, atleast with a goal difference.
Arsenal needs to keep winning to try to catch up with Liverpool. Even though they are far behind Liverpool looks strong and can not give up easily. At same time Fulham will probably lose but it is tempting to bet on them winning. Nottingham Forest and Manchester United seem to be equal in strength so tie is possible. However both teams have good chance of winning and it might be by just one goal. This match is going to be very competitive and hard to predict.
Arsenal have had several chances this season to close the gap between them and Liverpool, but their inconsistency has made them not make use of these chances, which has made it difficult for Arsenal to catch up with Liverpool in the Premier League table this season. If Liverpool should lose 3 consecutive matches now, they would still be topping the Premier League table, and no club in the Premier League can overtake Liverpool in the Premier League table, so Arsenal should focus on winning their matches to maintain their 2nd place in the Premier League table and leave catching up with Liverpool because it's not achievable this season.
I don't think there will be a team that can surpass Liverpool this season. We can say that Liverpool is the champion this year. Although it is not mathematically guaranteed that Liverpool will be the champion, the teams' possibilities still continue, but when you look at the matches played, if Liverpool plays like this, the probability of them becoming champions is very high. Because they don't lose points. If you don't lose points, you will be the champion. Being eliminated from the Champions League will also cause them to focus more on the Premier League. This will motivate them a lot and make their job easier on the way to the championship.
