The Blues were battered 3-0 by the Cherries on Wednesday night and Antonio Conte will demand a response from his side against the Hornets who have won just one of their last 12 Premier League matches.
Despite that defeat against Eddie Howe's side, the Blues can be backed at just 6/10 (1.60) with dabblebet to get back to winning ways when they visit Vicarage Road.
Javi Gracia would love to win his first home match in English football and the Hornets are chalked up as a 5/1 (6.0) chance with dabblebet to oblige.
The same firm go 3/1 (4.0) that both teams settle for a share of the spoils here.
Olivier Giroud is expected to make his Chelsea debut after completing a deadline day move to Stamford Bridge from Arsenal.
Gerard Deulofeu - on loan from Barcelona - could make his home debut for the Hornets.
Both teams to score?
Watford have found the net in each of their last eight matches on their own patch, although they have drawn a blank in their last three fixtures.
Chelsea, meanwhile, have scored nine goals in their last four away league matches, with four of those coming at Brighton.
Chelsea clean sheet?
The Blues can be backed at 23/20 (2.15) to keep a clean sheet against Watford, which would have landed in five of the last six matches that Conte's side have won inside 90 minutes.
They are also a 6/4 (2.50) chance to come out on top without conceding.
Tips and predictions
Chelsea will be desperate to produce a disciplined defensive display after that capitulation against the Cherries last time out, but the Hornets could hurt the Blues on home soil. As such, dabblebet's 17/20 (1.85) quote for goals at both ends may well prove to be a solid selection.
