Jose Mourinho felt a 2-2 draw at Chelsea was an "awful result" for Manchester United and a "phenomenal" one for Maurizio Sarri's men after Ross Barkley equalised in the 96th minute at Stamford Bridge.
Anthony Martial's second-half brace looked to have secured a superb win for Mourinho's men against his former club, with United coming from behind after Antonio Rudiger opened the scoring.
However, Chelsea substitute Barkley had the final say deep into stoppage time , the England midfielder's goal prompting wild celebrations on the touchline and a furious row as Mourinho was left incensed by provocation from Marco Ianni , a member of Chelsea's coaching staff.
