Troy Deeney is ready to give Prince William
'a bit of stick' when the pair meet at Wembley on Saturday for the FA Cup
Prince William, president of the Football Association, will be on hand before and after the game to meet both Manchester City and Watford players.
Deeney will captain the Hornets for the final and has revealed he is ready to take on the future king over his football allegiances.
'Yeah (he is) the future king, but I'm a Blues fan and he's a Villa fan so, I'll give him a bit of stick for that,' Deeney, a boyhood Birmingham City fan, told ESPN
. 'Everyone's telling me not to, but I think I'm going to have to.
'It's one of them games when, looking back on it now, from my background to meeting royalty (Prince William) and stuff like that, it's mental really when you think about it.'
Watford are standing between Manchester City and an unprecedented domestic treble with Pep Guardiola's team already holding the Carabao Cup and Premier League titles.
City go into the game as overwhelming favourites but after a thrilling comeback win against Wolves in the semi-finals, Deeney is 'proud' of the club regardless of the outcome on Saturday.
The Watford captain scored a vital late penalty to force the semi-final into extra-time before substitute Gerard Deulofeu booked a spot in the final.
'We are massive underdogs,' he said. 'But at the same time, I'm hugely proud of the achievement.'
Deeney's team-mate Kiko Femenia wants Watford to remain calm for the occasion and retain belief they can win the game.
In both league matches this season Watford lost, losing 2-1 at Vicarage Road and 3-1 away in Manchester.
'It's about staying together and being unified,' Femenia told the club's website
'Everyone has to do their bit. As a team we need to defend together and attack together and keep compact.
'In my experience Manchester City is more of a complete team than Barcelona, they have very fast players that can cause us problems. So it's just about making sure we keep together.'
