Etienne Capoue opened the scoring on 55 minutes when his strike sailed past the ‘keeper, and the goal was a reward for a positive first-half.
Heurelho Gomes produced a blunder, which allowed Michy Batshuayi to level the game with just 10 minutes to go.
Diego Costa completed the comeback with three minutes to go when he slid his shot under the body of Gomes as the Blues snatched the victory in the dying moments.
Walter Mazzarri’s men couldn’t replicate their heroics of the previous week, when they picked up their first point of the season, but see how the players got on against Antonio Conte’s men.
Strong afternoon for back three
Heurelho Gomes (5 out of 10) – Not a lot to do in the game, however, when he was called upon the most, his save from Eden Hazard’s shot allowed Batshuayi to tap into an empty net.
Sebastien Prodl (6 out of 10) – Was at fault for Costa’s winner, after letting the striker through on goal, but the defence did have a strong afternoon.
Craig Cathcart (6 out of 10) – Got the defence in line, and kept Chelsea’s aerial threats at bay, but the late substitutes changed the complexion of the game.
Miguel Britos (8 out of 10) – Stand out performer at the back, kept Costa quiet for most of the game, but swapped sides prior to the forward’s winner.
Midfield stood tall in game
Nordin Amrabat (7 out of 10) – Keeping summer signing Brice Dja Djedje out the side with some good displays, Amrabat produced another one today, looked threatening going forward.
Etienne Capoue (8 out of 10) – Second goal in as many games for the midfielder, who took his goal brilliantly, he has become a crucial part of Watford’s midfield.
Valon Behrami (8 out of 10) – Kept the gap between the defence and the midfield tight, Chelsea’s only shot of the first-half was a long-ranger from Hazard.
Adlene Guedioura (6 out of 10) – Didn’t play as well as he did against the Saints last week, but still put a shift in, but may be dropped for new signing Roberto Pereyra next week.
Jose Holebas (7 out of 10) – Along with Amrabat, the full-back provided attacks going forward frequently, kept Pedro quiet through the game.
Ighalo threatening up front
Troy Deeney (5 out of 10) – Another afternoon to forget for the Hornets’ skipper, who looked off the pace once more on Saturday.
Odion Ighalo (7 out of 10) – After a poor display against the Saints, last season’s top-scorer saw more of the ball and looked dangerous.
Substitutes made too late to make impact
Abdoulaye Doucoure (N/A) – Came on for Capoue on 84 minutes, too late to make any sort of impact.
Matej Vydra (N/A) – Brought on for Guedioura after Costa’s winner went in, too little too late though.
Juan Camilo Zuniga (N/A) – Again all the substitutes were made too late, the wing-back replaced Holebas with minutes remaining.
