Watford are huge underdogs this weekend as they try to pull off an FA Cup giantkilling and ruin Manchester City’s quadruple bid.

City have been flying on all fronts this season and have won every home match except for their Champions League defeat to holders Bayern Munich.

Keeping the score down is probably the realistic target for the Hornets with the Premier League side rattling in more than 100 goals this campaign.

Manuel Pellegrini’s side are prohibitive 1/10 favourites with Paddy Power while even the most optimistic Watford fan will surely be kidding themselves if they back an away win at 25/1.

But if you feel like donating to the bookies then Watford to win 3-2 at the Eithad Stadium is 250/1 with Coral. How about a speculative pound on Lloyd Doyley to get the final goal? Ladbrokes will be more than happy to take your money at 150/1.

The Hornets have drawn their last seven matches away from home so if you fancy this trend to continue Labrokes are offering 9/1 on this unlikely result.

City have scored 15 goals in their last three home matches, including a 5-0 thrashing of Blackburn Rovers in their third round replay and have averaged four goals a game at the Etihad.

It could be worth throwing a few pounds on over 4.5 goals at 2/1 with William Hill while the more cautious punter might back over 3.5 goals at 4/5.

Edin Dzeko netted twice in the previous round so the striker could be worth backing to net two or more goals at 11/4 with Betfred.
