Ref right to show second card, says Mourinho
The Dutchman was dismissed after over-celebrating his decisive 69th-minute strike after being booked for a first-half foul as the Barclays Premiership leaders came from behind to see off a spirited Sunderland side.
Robben was devastated to receive his marching orders, but Mourinho, who offered him a consoling handshake as he left the pitch, said the official had no choice with the second yellow card, if believing the first was harsh.
