Brighton is playing United away so will probably lose, but Fulham is running out of time to catch up. If they lose today, they will have 5 games left to close a 7-point gap, which sounds almost impossible.
Considering they are playing Arsenal, over 2,5 goals sounds like a good bet to take. Fulham will probably try to play a tight and defensive game, but if Arsenal scores they will have to hunt the game down.
Arsenal have still a chance for the 5th spot even if there is a 9-point gap. So, I suppose they will try their best in the remaining games including this one. Fulham's chances also exist for staying in the PL. I expect a delightful game.
I think both sides will score. And Arsenal will be victorious by 1 goal.
