Watford boss Walter Mazzarri is unsure what the repercussions of Alan Pardew's sacking by Crystal Palace will be for his own team.
The Hornets have been preparing to face their Premier League rivals at Vicarage Road on Boxing Day, but the fixture has taken an unexpected twist after Pardew was dismissed in reaction to a run of one win in 11 league matches.
"We cannot know if it will help us. There could be some changes, but it could also be a disadvantage for us," Mazzarri said.
"When this happens I am not happy because, at the end of the day, managers are colleagues, but this is football and it's only the managers who pay the final price.
