A win for the Hornets would condemn Norwich to an instant return to the Championship, although events at Carrow Road will be rendered irrelevant should Sunderland send the Canaries and Newcastle down with victory over Everton at the Stadium of Light.
Despite leading his side to a FA Cup semi-final and Premier League safety, Flores has found himself at the centre of fervent speculation recently, with reports suggesting he is to hold talks with the club's owners over the next few weeks.
But he insists he is nonetheless eager to finish the season with a flourish, and potentially compound the relegation worries of both Norwich and Sunderland in the process, with the latter travelling to Vicarage Road on the last day of the season.
According to the Mirror, he told his pre-match press conference: “I don't like to play against Norwich and Sunderland in our last two games because they are fighting relegation and it is sad that they have suffered a lot over the season.
“But in this case we are the bad boys in the film – we know our role and we need to play it.
"It's necessary to be serious in this kind of match and not relaxed. We are not fighting for other teams, we have to respect ourselves.
But while Flores is keen for his side to show no mercy to their struggling opponents, he insists his team will remain respectful.
“You have to play with integrity and, if relegation follows, you need to give your condolences afterwards and say sorry. It's very sad.”
