Walter Mazzarri believes Watford will face a "very angry'' Manchester City when they head to the Etihad Stadium on Wednesday night.
City slumped to a 4-2 defeat at champions Leicester on Saturday, which saw them finish the weekend in fourth place, some seven points behind leaders Chelsea.
Although the Hornets come into the match full of confidence following their 3-2 home win over Everton, manager Mazzarri is expecting a reaction from Pep Guardiola's men.
"I saw the game against Leicester. I was surprised, but in Italy we have a saying: 'Each game has its own story','' Mazzarri said at a press conference.
