Hello and welcome to our live coverage of the 2019 FA Cup final as Manchester City face Watford.
Manchester City vs Watford: preview
Can Manchester City become the first English side to claim the domestic treble becoming winners of the domestic championship and both League and FA Cup?
Watford stand in the way of Pep Guardiola's men writing a new chapter of history in the annals of the English game. Meetings between both teams this season in the Premier League auger well for the Sky Blues with a 1-2 win at Vicarage Road and a 3-1 home win for Guardiola over Javia Gracia's Hornets.
City start as firm favourites ahead of the Wembley showpiece final something acknowledged by Hornet's Troy Deeney who stated:
"We're massive underdogs, but at the same time, I'm hugely proud of the achievement," Deeney added. "For me, it's no fear. Look at everything we just spoke about. Football isn't going to scare me or playing against City... because of everything I've been through."
Watford lost 2-0 to Everton in 1984 in their previous appearance in the FA Cup final. City will be looking for their sixth FA Cup with the last title coming during the 2010-11 season.
