Arsenal are odds-on favourites to win at Watford in the Premier League tomorrow.

Walter Mazzarri is still searching for his first win in charge and the hosts are available at 15/4 (Coral) to defeat the Gunners.

Arsene Wenger's side also only have one point from their first two league games but are 8/11 (Ladbrokes) to get off the mark at Vicarage Road.

The draw is 11/4 (Coral) but this has not occurred in the last 15 meetings dating back to 1984.

It is hard to back the Hornets with confidence after failing to hold onto the lead in their three matches this season.

But it could be worth taking 7/4 with Betfred on Watford scoring the first goal, judging by the way their opening games have panned out. 

The last two times Arsenal have played at Watford, the Gunners have been level at the break and won at full time.

There could be some value in backing the draw at half-time and Arsenal at full-time at 7/2 with Ladbrokes.

Roberto Pereyra could make his Hornets debut and the attacking midfielder is available at 13/2 with Paddy Power to score.
