Chelsea strengthened their top four hopes by beating Watford at Stamford Bridge on Saturday night.
Manchester United’s win over Bournemouth earlier in the day had seen the Blues slip to fifth place, but a 3-0 victory ensured they reclaimed fourth from the Red Devils.
Both goals came in the first half. Olivier Giroud opened the scoring with a smart first-time finish on the turn, just before the half-hour mark.
And as the break approached, Christian Pulisic was brought down in the box to win a penalty for the hosts. Willian stepped up to convert his third spot kick in three games.
That made 2019-20 Willian’s most prolific Premier League season in a Chelsea shirt, while he also became just the sixth player in the competition’s history to score penalties in three successive matches.
Ross Barkley scored in stoppage time of the second half to make it 3-0, as Chelsea held on to return to the final Champions League spot.
Lampard had demanded atonement for Wednesday’s shock loss at West Ham, and his focused Chelsea charges delivered against an admittedly-limited Watford outfit.
Stamford Bridge has been awash for weeks with talk of a summer signings revolution, but here it was the old guard who came good for Lampard.
Giroud recently signed a one-year contract extension, but he will face extra competition next term in the shape of £53million RB Leipzig recruit and prolific Germany hitman Timo Werner.
The 31-year-old Willian continues to hold out for three years on a new deal, whereas Chelsea only want to offer him two.
But the 70-cap Brazil star now boasts 11 goals in all competitions this term, and three in two matches after his brace amid that galling loss at West Ham.
Lampard has made no secret of his desire to retain Willian’s services next term, and the well-liked winger has doubtless again boosted his chances of a new Blues contract.
Kepa’s awkward pass left the double-marked Andreas Christensen in hot water on the edge of his own box in an inauspicious start.
The Dane rode out of trouble well enough and once the Blues settled they took control.
Christian Pulisic again matched industry with invention, the 21-year-old again proving vital to Chelsea’s attacking rhythm and shape.
The United States forward slipped Giroud in on the inside left but the Frenchman could not stretch Ben Foster in the Watford goal.
Mere minutes later Giroud pounced on the opportunity to make amends, drilling home from almost the same position.
This time it was Barkley who slid Giroud through, with the 33-year-old making no mistake in leaving Foster with no chance.
Watford’s deep double-bank defending continually invited Chelsea to attack, and once in the lead the Blues moved with more fluency and comfort.
Pulisic caused panic in the Hornets’ box, inciting a clumsy challenge from Etienne Capoue – and a penalty was the only outcome.
So up stepped Willian, stroking into the net after his now-customary stuttering run-up.
Chelsea continued to dominate after the break, and Willian scythed through Watford’s cover before sending a cute ball through for Giroud.
The Blues striker found the target once more but Foster conjured a solid save.
Willian’s dipping 20-yard drive drew another good stop from Foster. Kurt Zouma connected well from the resulting corner but his header was straight at the Watford goalkeeper.
Late on Danny Welbeck squandered Watford’s only real chance of the night, with Kepa Arrizabalaga pulling off a good save from the striker’s low shot.
Chelsea were denied a second penalty at the death, with Christian Kabasele judged not to have felled the marauding Pulisic after a video assistant referee check.
Just when the Blues were expecting to settle for a goalless second-half though, up popped the in-form Barkley with a smart strike to seal the comprehensive Chelsea win.
