A night of 'carnage' at Stamford Bridge saw the Video Assistant Referee system branded a 'shambles' and 'shocking' as Chelsea relied on penalties to beat Norwich in their FA Cup replay.
The third-round tie went the distance after a 90th-minute header from 19-year-old Jamal Lewis cancelled out Michy Batshuayi's opener in normal time.
Yet the game was then overshadowed by controversy as referee Graham Scott denied Chelsea what they felt was a clear penalty and sent off Pedro then Alvaro Morata.
In the first half of extra time, Willian was booked after being judged to have dived in the box, though television replays showed there was contact from Timm Klose.
