The super sub bailed out his struggling team-mate as Enzo Maresca's side took command of this Conference League quarter-final tie
Noni Madueke scored two goals off the bench as a strong second-half showing secured Chelsea a 3-0 win against Legia Warsaw on Thursday.
The Blues had 75 per cent possession and fashioned nine shots to the hosts' three, but could not find a way through in the first half.
Kiernan Dewsbury-Hall's curling effort was expertly pushed away by goalkeeper Kacper Tobiasz, and Rafał Augustyniak did well to stop Christopher Nkunku from turning the ball home from close range.
At the other end, Max Oydele played a delightful through ball to find Ryota Morishita but the Japanese forward couldn't keep his effort on target when in a good position.
Maresca's half-time team talk seemingly worked wonders as 19-year-old Tyrique George scored his first goal for the club after Reece James' shot wasn't held by Tobiasz in the 49th minute.
It was 2-0 just eight minutes later when Jadon Sancho found substitute Madueke in the box, and the winger finished with aplomb.
Mere moments after Nkunku failed to convert he penalty he won, Sancho set up Madueke again from close range to make it 3-0 with 16 minutes remaining.
Patryk Kun brought a great reaction stop out of Filip Jorgensen at the death as Chelsea took a hefty advantage into the second leg of this Conference League quarter-final tie.

Getty Images SportGoalkeeper & Defence
Filip Jorgensen (6/10):
Had very little to do all night but made a good reaction save late on to preserve his team's clean sheet.
Josh Acheampong (7/10):
Was eager to get forward at every opportunity and looked very composed on the ball.
Tosin Adarabioyo (6/10):
Made some nice passes into attack and didn't do much wrong. But was surprisingly taken off at half time.
Benoit Badiashile (7/10):
Used his height to good effect, both in attack and defence. Past the test that came his way.
Malo Gusto (7/10):
The consistent performer did nothing to hurt that reputation in what was a very hostile atmosphere.

Reece James (8/10):
Was a creative force in midfield, played his part in Chelsea's first and second goals, and led by example as captain.
Kiernan Dewsbury-Hall (6/10):
Got himself into dangerous positions but missed a number of decent chances to put his side ahead. Not a bad display, mind.
Cole Palmer (6/10):
He showed some positive signs but this is not the same player that was tearing up the Premier League earlier this season.

Jadon Sancho (7/10):
Didn't offer a great deal in the opening 45 minutes but was much more of a threat after the interval, as he went onto chalk up two assists.
Christopher Nkunku (4/10):
He didn't provide the forward presence Chelsea needed, particularly in the first half, and his penalty miss was telling. The Frenchman's confidence seems quite low right now.
Tyrique George (8/10):
The teenager showed plenty of vigour and quality and showed good attacking instincts to get his first ever goal for the club he has been at since 2014. Did well as a winger and a number 10.
Getty Images SportSubs & Manager
Levi Colwill (7/10):
Mopped up everything that came his way when he came off the bench.
Noni Madueke (9/10):
Had an instant impact when he came on and took his two goals with ease.
Marc Cucurella (7/10):
Was very composed when his team called upon him.
Mathis Amougou (6/10):
Wasn't afraid to get stuck in.
Shim Mheuka (6/10):
The youngster was energetic off the bench.
Enzo Maresca (7/10):
His side lacked ideas and weren't really at the races in the first half but were much improved after the break and his substitutes did the trick.
