Arsenal icon Thierry Henry hailed Manchester United as they cut Swansea apart with a ruthless display of counter-attacking football in Saturday's 4-0 win.
Eric Bailly had given United a first-half lead at Liberty Stadium with a close-range volley after Lucasz Fabianski had tipped Paul Pogba's header onto the bar.
United looked secure as they wore the Swans down in the second half, but late substitutions from Mourinho saw the Red Devils take the game up a notch.
The introduction of Anthony Martial's speed and Marouane Fellaini's strength 15 minutes from the end saw United score three goals in six minutes, with Romelu Lukaku, Pogba and Martial finishing off counter-attacks that Swansea had no answer for.
Arsenal legend Henry was impressed with United's strength and speed at Liberty Stadium, telling Sky Sports: "The size, the power, the pace... I mean we talked about it the other day against West Ham.
"When you look at [Henrikh] Mkhitaryan (who added two assists to his double against West Ham), he's not that tall, he's not that strong, but when he went on the break, when he gave that goal to Pogba, the pace and the awareness!
"Something you need to understand is that people talk about [strength], pace and physical abilities... those guys can play, and see, and execute stuff that most people cannot - especially in transition."
The win will keep United top of the Premier League table unless one of their rivals secures a huge result this weekend.
