Alexis Sanchez has stepped up his battle to be fit for Manchester United's suddenly crucial home clash with Tottenham on Monday.
The Chilean missed United’s miserable 3-2 defeat at Brighton at the weekend because of an injury.
Sanchez played the full 90 minutes in United's season-opening 2-1 win over Leicester - his 19th appearance for the club he has so far scored only three goals for.
Posting from the gym, he declared he was "training to be back soon", adding "Come on United".
Mourinho hopes Sanchez’s return will spark his team into life.
