Everton goalkeeper Jordan Pickford excelled in front of watching England manager Gareth Southgate as Sam Allardyce’s men stretched their unbeaten run to seven games.With Wayne Rooney absent through illness, Everton soaked up plenty of pressure from Antonio Conte’s men with Pickford making excellent stops to deny Eden Hazard and Pedro twice.In addition, skipper Phil Jagielka cleared off the line twice in the same attack and Everton escaped when Ashley Williams headed against his own goalpost.While Conte will be pleased with his third-place side’s overall performance – Everton failed to register a single shot on target - the visitors missed suspended striker Alvaro Morata with Hazard playing as a false No 9 for most of the game until Michy Batshuayi came on for the final 20 minutes.A flu bug meant Rooney wasn’t involved, though Williams and Mason Holgate clambered off their sickbed to be among the substitutes.Allardyce tried to combat Chelsea by pushing Idrissa Gueye in advance of Morgan Schneiderlin, hoping to put pressure on N’Golo Kante and Tiemoue Bakayoko.But Chelsea will feel they still had enough of the ball to have returned to London with the points.Everton’s first hero was 35-year-old Jagielka starting his first game under Allardyce.After Hazard had whipped a dangerous ball into the Everton box, Jagielka was on the line to block Bakayoko’s shot after it had beaten goalkeeper Pickford.And when Willian followed up the rebound, the same player was there to clear again.In a nice touch, Davies ran over to his experienced colleague to shake his hand as a thank you for keeping the home side level.It appeared Allardyce’s tactics centred on stopping Chelsea’s left wing-back Marcos Alonso.On the other flank, Victor Moses was afforded a lot of space and Cuco Martina was booked when he had to sprint across and bring down the Nigerian international on the edge of the box.Fortunately for Everton, Willian took the free-kick rather than Alonso and blazed the 22nd minute chance over.Pickford first got his chance to show Southgate what he can do after 35 minutes when he got a strong hand to tip over Pedro’s well-struck effort as it headed towards the top corner.Hazard started roaming more to the left-hand side towards the end of the first half having had little joy down the middle.One thrilling run saw him beat three defenders but he let his frustration show when no Chelsea team-mate showed for the ball and he eventually lost possession.There was one late scare when Calvert-Lewin muscled Thomas Christiansen off the ball and dashed into area before the visitors got reinforcements back to block.Allardyce made two changes at half-time, Ashley Williams and Sandro Ramirez on for Lennon and Davies as Everton went to three-at-the-back.It nearly backfired immediately when Pickford had to make a terrific reflex save from Pedro and Williams reacted well to block Alonso’s follow-up.Allardyce must have cursed his luck when Gueye then limped off after 51 minutes forcing
