•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.
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.

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.
United survived in relative comfort apart from a big late chance for Antonio Rudiger and will regard this as a welcome point in tough territory after a succession of Premier League horror shows led to Ole Gunnar Solskjaer's sacking.
Carrick went with solidity for his first Premier League team selection after United's recent maulings by Leicester City, Liverpool, Manchester City and - finally for Solskjaer - Watford.
He bolstered midfield by utilising Fred, Scott McTominay and Nemanja Matic to hold Chelsea at bay and, while David de Gea was busy in the first half, there was never a feeling of siege as United dug deep to come away with a point.
The big call was keeping Ronaldo on the bench. He was introduced with United leading 1-0, but had minimal impact and was straight off down the tunnel when the final whistle sounded.
United at least showed the determination and resilience that had so often been glaringly absent in the dying embers of Solskjaer's reign although there was very little attacking intent or quality apart from the great composure shown by Sancho for his second successive goal.
It will do him the world of good as he seeks to establish himself following his £73m summer move from Borussia Dortmund.
As for Carrick, if this is his final game in charge before Rangnick comes to Old Trafford, he can be well satisfied with his brief stint at the helm, winning against Villarreal in the Champions League and getting a share of the spoils here against a Chelsea side who have looked increasingly formidable in recent weeks.
It is a platform of sorts for Rangnick to begin his work and United will hope to continue their recovery against Arsenal at Old Trafford on Thursday.
