The result came as a shock considering Mourinho’s renowned defensive ideology and United’s stern 0-0 draw against Liverpool.
But pundit Redknapp has hit out at the Red Devils chief, claiming he must change his tactics to suit the traditions of United.
“What was the point of Jose Mourinho signing creative, exciting players like Paul Pogba and Henrikh Mkhitaryan if he’s going to play so negatively?” Redknapp.
“This is a talented Manchester United squad but they should be going toe-to-toe with Chelsea, not setting up to try to get a draw.
“In the first half, Jesse Lingard and Marcus Rashford were playing as extra defenders in a back six. It’s too defensive and the players aren’t able to express themselves.
“People are saying that the players have to adapt to Jose’s style but I disagree. He must change to suit the traditions of a club that produced the most exciting team of the last 20 years.”
