The former Benfica and Atletico Madrid coach was forced to play down the whispers about his job yesterday, insisting they will not distract his side.
But they come at a bad time for Watford, who are hoping to reach their first FA Cup final since 1984.
Flores said: “We are focused on this weekend. What is important is that everything can see Watford playing at Wembley and I want to enjoy it.
“It’s amazing for the players the club and for me. I’m excited to visit Wembley for the first time. I have visited a lot of good stadiums in my life but this is a new one. It’s an honour for me.”
