Chelsea claimed an early lead at Norwich as Tammy Abraham repaid the faith shown in him by Frank Lampard.
The striker had been criticised for missing the penalty which saw Chelsea lose a penalty shoot-out to Liverpool in the European Super Cup but he made no mistake against Norwich, volleying home a cross by Cesar Azpilicueta with three minutes gone.
But just three minutes later Norwich levelled the scores as the prolific Teemu Pukki became provider when Todd Cantwell turned in his low ball from close range.
Norwich: Krul, Aarons, Godfrey, Hanley, Leitner, Lewis, Cantwell, Buendia, Stiepermann, Trybull, Pukki.
Subs: Fahrmann, Byram, Vrancic, Klose, McLean, Tettey, Srbeny
Chelsea: Kepa, Azpilicueta, Christensen, Zouma, Emerson, Kovacic, Jorginho, Mount, Barkley, Abraham, Pulisic.
Subs: Caballero, Tomori, Alonso, Willian, Giroud, Batshuayi
