The Hornets captain says his side must not get used to losing otherwise they may end up like the Magpies.
Watford captain Troy Deeney has urged his side not to allow themselves to become accustomed to losing and highlighted the plight of Newcastle United as a dire warning sign, as quoted by the London Evening Standard.
The Hornets have, on the whole, enjoyed a successful first season back in the Premier League after their promotion last term, virtually assuring their safety at the halfway point of the campaign thanks to fine run which saw them lose just five of their first 18 league matches.
However, it has been a different story in 2016; Quique Sanchez Flores' side have won only four of their 18 fixtures since Boxing Day, although they did reach the FA Cup semi-finals, and did not secure three points for two months between 13 February and 16 April.
In that second set of 18 matches, Deeney's team have endured defeat on 10 occasions, and the captain stressed that Watford cannot allow themselves to simply slide into a losing mentality if they are to be a Premier League team for the long term.
The long-serving striker also highlighted that the plight of Newcastle, who look on the verge of a second relegation in eight years, should serve as a stark warning to Hornets players.
Deeney said, as quoted by the Standard: "It’s easy to switch off but I’ve been drilling it home to the lads in the dressing room that we just can’t.
"If you look at Leicester, they ended last season unbelievably well. I’m not saying we’re going to win the league by any means but they carried on their form into this year.
"On the flip side Newcastle did poorly last year and it’s carried on into this. You can get used to losing so that mentality will never happen as long as I’m here. We’ll never get used to losing."
Watford, who are currently 13th in the Premier League table and just four points off a place in the top half, have two games against relegation battlers as their final two fixtures, with a trip to Norwich City followed by a home clash with Sunderland.
