Walter Mazzarri has warned Watford not to underestimate a Swansea side he believes to be languishing in a false Premier League position.
Hinting that former boss Francesco Guidolin was unlucky to have been sacked and replaced by American Bob Bradley, Hornets manager Mazzarri praised the Welsh club's style of play.
Swansea lie 19th in the table going into the game, but Mazzarri has told his players not to be fooled and has been impressed by the Liberty Stadium outfit all season.
'Even under Francesco Guidolin they were playing good football for many moments, so they are a very good team and in their stadium it's a team we have to be aware of,' said Mazzarri.
