This was the weekend that the Premier League title became Chelsea’s to lose as Antonio Conte’s men extended their lead to eight points and Diego Costa made a goalscoring return to the team.
Only Arsenal’s late winner against Burnley prevented what would have amounted to a perfect 48 hours for Chelsea, who had seen Liverpool, Tottenham Hotspur, Manchester City and Manchester United all drop points.
But, regardless of Arsenal’s three points, Chelsea are looking more and more like champions elect as they secured their 15th victory in 16 Premier League games.
This is only the fourth time a club have amassed 55 points or more after 22 Premier League games and on the two previous occasions Chelsea have, in 2004/05 and 2005/06, they have won the title.
Should the Blues come through their next two Premier League games against Liverpool and Arsenal unscathed then there will surely be no stopping Conte’s relentless side.
They were a long way from their best against relegation battlers Hull City but, unlike many of their rivals, Chelsea have the ability to grind out victories when they are tested.
Conte’s men also keep clean sheets. This was their 13th of the season and goalkeeper Thibaut Courtois was busier than many people would have predicted.
The Chelsea fans like to sing about the magic hat of Cesc Fabregas, but it was the magic touch of Conte that was once again evident against Hull.
His handling of the Costa situation proved to be spot on, as the striker marked his 100th appearance with a vital goal and, at least for now, drew a line under the bust-up over a back injury and a lucrative offer from China that had seen him miss the victory over Leicester City.
Aside from getting his Costa decision right, Conte made the perfect substitution late on when Chelsea were under pressure, as he sent on Fabregas and the midfielder provided the free-kick from which Gary Cahill headed the second goal.
All the pre-match attention had focused on Costa, who quickly demonstrated that his back was feeling just fine with a volley that bounced narrowly wide after just 10 seconds.
The Stamford Bridge crowd had reacted positively to Costa’s name when it was read out before kick-off and they used a break in play following a clash of heads between Cahill and Ryan Mason to reaffirm their support for the club’s top scorer.
Costa waved back as his name was chanted and medics administered oxygen to Mason, who left the pitch on a stretcher after eight minutes of treatment.
David Meyler replaced Mason, who was taken to St Mary’s Hospital for further treatment and tests, and it was during the nine minutes of time added on largely for his injury that Costa put Chelsea ahead.
In the seventh minute of injury-time, Marcos Alonso swept the ball out to Victor Moses on the right whose low cross was side-footed into the net by Costa while Hull were complaining about a Cahill foul on Abel Hernández. Responding to over a week of stories regarding his row and Leicester no-show, Costa celebrated by making a talking gesture into both ears.
He clearly likes to be the centre of attention and Conte will hope all the talk is now about the 28-year-old’s goals for the remainder of the campaign. Before Costa’s opener, the impressive Harry Maguire had gone close for Hull. First, he headed straight at Courtois from a corner and the Belgian did even better to push a shot from the defender around the post.
Curtis Davies was perhaps lucky to come out for the second half, having escaped a second booking for a foul on Pedro towards the end of the first period.
Chelsea were even more fortunate that a penalty was not awarded against them four minutes after the restart when Alonso clearly clipped the heel of Hernandez, but the protests of Hull manager Marco Silva were ignored by referee Neil Swarbrick.
Meyler then forced Courtois into a low save with a powerful driven shot as Hull started the second half brightly. Davies did come off on the hour mark with an injury, as Silva replaced the defender with on-loan striker Oumar Niasse in an attempt to find an equaliser.
With Chelsea failing to keep the ball and inviting pressure on to themselves, an increasingly frustrated Conte made two changes of his own by sending on Fabregas and Willian.
The double switch paid dividends with 10 minutes remaining, as Fabregas sent in a free-kick from the left that Cahill headed past Eldin Jakupovic to secure another valuable win.
Conte, as he always does, celebrated wildly, but Silva will not have been quite so impressed with the impact of his own substitute Niasse, who had ducked under the set piece of Fabregas to gift Cahill what amounted to a free header.
Costa should have extended Chelsea’s advantage even further when he was sent through by Fabregas, but the Spain international could not beat Jakupovic and left to a standing ovation when he was replaced by Michy Batshuayi.
Conte’s rivals will be wondering if he will ever make a wrong call over the remaining months of the season. It may already be too late for them, even if he does.
