A return under pressure: the five problems Mourinho must solve on his visit to Camp Nou

José Mourinho faces several challenges in his return to Camp Nou, including the absence of Vinícius, a six-point gap with Barcelona, and managing controversies. The Portuguese coach must adapt his strategy without Vinícius, who is suspended, and address the pressure of trailing Barcelona, who have won all their league matches. Additionally, Mourinho must navigate the ongoing referee controversies that have resurfaced with his return, as well as manage the dynamics within the squad, particularly concerning Kylian Mbappé's recent behavior. Lastly, he needs to make tactical decisions regarding his midfield setup against a strong Barcelona side.
