The Manchester United boss took to Instagram to pay tribute to his countrymen who stunned the hosts in Paris
Fernando Santos' men stunned the hosts in Paris as substitute Eder stepped off the bench to fire home an extra-time winner.
It came despite talismanic skipper Cristiano Ronaldo going off with a knee injury inside 25 minutes.
Portugal, who managed just one win in normal time throughout their seven games at the tournament and only finished third in their first-phase group, delivered a resolute display against the odds.
And as their fans celebrated long into the night, Mourinho took to Instagram to pay tribute.
The Manchester United boss uploaded a picture of himself, appearing to be in his pyjamas, holding a Portugal scarf aloft.
The caption read: "If you want to visit the country of the european champions visit PORTUGAL!!!!"
The Real Madrid superstar was in clear discomfort after a heavy challenge from Dimitri Payet, but initially refused to leave the field.
After eventually conceding his time was up, he was later seen giving a team-talk to his side before issuing instructions from the touchline technical area during the extra-time period.
