Kylian Mbappe, Jude Bellingham and Marc Cucurella all make the trip to Catalonia despite a reduced preseason campaign following their post 2026 FIFA World Cup breaks.
However, Mbappe's French teammate Aurelien Tchouameni misses out due to injury, and Liverpool target Endrick is also absent.
The duo are both not included by Mourinho due to 'minor physical issues' - but speculation continues to grow over an incoming Anfield offer for the Brazilian.
The 20-year-old spent the second half of last season on loan at French side Lyon after struggling for a role at Real Madrid.
He impressed at the Ligue 1 club, scoring eight goals and providing eight assists across 21 games in all competitions, and Liverpool have reached out regarding his availability.
Real Madrid are not interested in a sale - and Mourinho could still utilise him as a first team option - as Liverpool chase a right-sided attacker after seeing a £60M bid for Brighton’s Yankuba Minteh rejected.
