The former Red Devils captain wasn't inspired by the Portuguese's tactics en route to squeezing past Celta Vigo on Thursday
Manchester United legend Roy Keane has criticised Jose Mourinho's defensive mindset in advancing to the Europa League final, saying the Red Devils "need to be more ruthless."
United were largely outplayed by Celta Vigo in their semi-final second leg on Thursday at Old Trafford, but Mourinho's men managed to hang on for a 1-1 draw and triumphed 2-1 on aggregate.
And Keane, a former United captain who played for the club from 1993 to 2005, was not inspired by the performance.
