My first thoughts were, Under 2.5 goals is a Fix. Both teams score less than 2.5 goals in more than 50% games, Aston Villa scoring only 1 goal in last two games.
But then I started thinking that this time it will be different. There is only one match played and as soon as one team scores, the other will need to open and attack with all means. Fulham will score first, probably in first half already. Aston Villa will open and either score or concede because of vulnerability in defence. My tip is Over 2.5 goals. If you're brave you can try exact result 2:1.
