In their previous meeting just over 3 weeks ago, Watford stole away Arsenals hopes of winning any silverware this season by beating them 1-2 in the FA cup quarter finals.
This game is surely the perfect opportunity for Arsenal to come back with a vengeance.
If Arsenal carry on their mentality and dominance like they did in their clash at Goodison Park against Everton, they have every chance of beating the Hornets.
The key to beating Watford lies in Wengers team selection and who he decides to start on the day. The starting 11 against Everton was the best selection I have seen all season.
Welbeck is in sensational form, scoring 4 goals in 9 games since his return from a knee injury in February. It would be a no brainer to start Welbeck over Giroud. Giroud is in poor form at the moment and Wenger needs to relish the fact that Welbeck is on fire.
Another key player that pairs up well with Welbeck is the 19 year old Nigerian International Alex Iwobi. Iwobi has shown great potential after Wenger put him up on the big stage by selecting him in the starting 11 against Barcelona at Nou Camp. He also made a big impact in the game against Everton by scoring a wonderful second goal for the Gunners on the brink of half time.
Arsenal cannot afford defensive errors
Igahalo will cause problems for Arsenal. His pace and creativity could see Arsenals defence make crucial errors that may cost them any chance of a real title race. This is why Mertesacker should be benched over Gabriel. In the past he has cost Arsenal points and is known for causing defensive problems. Gabriel still has a lot to learn but he has the pace and the aggression that Mertesacker clearly lacks.
Cech returns from injury
Ospina has been the unspoken hero for Arsenal after replacing Petr Cech who was out with a groin injury for a month. His save against Lukaku was phenomenal and his performances all around have been outstanding. But Cech is set to return from injury this weekend so we should expect to see his name in the starting 11.
