Manchester United prepared for the arrival of interim manager Ralf Rangnick by earning a battling point against Premier League leaders Chelsea at Stamford Bridge.
United, under the caretaker charge of Michael Carrick with Rangnick's appointment expected to be confirmed imminently, kept Cristiano Ronaldo on the bench and mounted a largely rearguard action until Jadon Sancho hit Chelsea on the break five minutes after half-time.
Sancho pounced on poor control from Jorginho to race clear and beat Edouard Mendy with a composed finish after the hosts had dominated possession.
Chelsea were stung into action and Jorginho made amends for his error when he equalised from the spot in the 69th minute after Aaron Wan-Bissaka fouled Thiago Silva.
