Paul Clement's arrival at the Liberty Stadium in January finally looked to have arrested a Swansea decline which can be traced all the way back to the start of last season.
A late surge at the end of 2015/16 saw them to safety, and it appeared an earlier one this season - with victories against Liverpool and Southampton to name but two - would prove similarly fruitful.
But a sudden drop in form, with one point from the Swans' last five games, coupled with some good result for relegation rivals' Hull City, has cast them two points adrift of the pack with just six games to go in the Premier League.
Clement's side will be fighting for their lives at Vicarage Road later - but, as a classy Spurs side demonstrated 10 days ago, they have a soft underbelly and the Swansea head coach has already had to deny his side are 'anxious' in the build-up to today's game.
The form book
This doesn't look good for Swansea. Clement won three of his first four games at the helm at the Liberty Stadium but since then, narrow home wins over out-of-form Burnley and Leicester have been as good as it gets.
A stalemate with Middlesbrough in south Wales is the only thing Clement's men have to show for their efforts in their past five games and with Stoke City, Manchester United and Everton to face in their three games after today, getting something at Vicarage Road will be crucial to their survival hopes.
Influential midfielder Jack Cork will be missing for Swansea, having twisted his ankle in their defeat to West Ham last weekend.
But Fernando Llorente, who came on at half-time at the London Stadium, will be pushing for a first start since March 18, and could prove a real handful for the Hornets' defence if he is on form.
Man to mark
Gylfi Sigurdsson doesn't disappoint in a Swans shirt, and is joint level of the assist charts with Kevin De Bruyne and Christian Eriksen despite their lowly position.
Keeping the ball out of the Watford onion bag will be largely dependent on how the Hornets deal with the infuential Icelandic playmaker, who has started all but one of their Premier League games this season.
The Watford connection
The Hornets won their last game at Vicarage Road against the Swans, courtesy of Odion Ighalo's second-half strike in a 1-0 win last season - their first victory back in the Premier League, and despite Valon Behrami's red card.
Unfortunately, that is Watford's only win in the two sides' last seven encounters - with Swansea earning a 0-0 draw at the Liberty Stadium this season, and beating the Hornets 1-0 at home last season.
What they've said
Clement said only the Swans can control their own destiny, and cast aside worries over Hull's recent improvement on the pitch.
He said: “We can’t focus on anyone else or anything else. We can’t worry about who other teams are playing or what they are doing.
“We just have to focus on what we can affect, which is our own performances. I don’t want the players to have fear about the result or about what could happen at the end of the season.
“For us it’s about focusing on the task in hand and that is our game at Watford.”
