Real Madrid manager Jose Mourinho is reportedly planning to study Barcelona’s Champions League encounter against Paris Saint-Germain closely as he prepares for the upcoming El Clasico.

According to a report by Barca Universal on Tuesday, October 20, 2026, the Portuguese coach is particularly interested in how Hansi Flick organises Barcelona’s defence while dealing with injury concerns ahead of Sunday’s meeting between the Spanish giants.

Barcelona face uncertainty over the availability of Jules Kounde and Eric Garcia, both of whom have played important roles on the right side of the defence this season. Their potential absences could force Flick to make tactical adjustments against PSG, providing Mourinho with an opportunity to assess the alternatives available to his former rivals.

The Real Madrid manager is expected to examine how Barcelona cope defensively against a strong opponent, especially if they are unable to field their preferred backline. The French champions’ attacking quality could test Flick’s defensive organisation and expose weaknesses that Madrid might seek to exploit in the Clasico.

Although Mourinho is already familiar with Barcelona’s playing style and attacking strengths, the team’s response to these fitness problems could offer fresh insight into their current tactical setup.

Kounde’s availability will be particularly important, as his return would give Flick additional options and greater stability at the back. If the defender remains unavailable, Barcelona may have to rely on alternative arrangements, potentially influencing how they approach the encounter with Real Madrid.

However, Barcelona will be determined to show that their defensive structure can withstand the pressure despite the injury setbacks. A strong display against PSG would provide Flick with valuable reassurance about his squad’s ability to handle difficult challenges ahead of the domestic showdown.

With the European fixture followed by one of the biggest matches on the Spanish football calendar, Flick must also balance the demands of competing in the Champions League with the need to keep his players fit for El Clasico.

Mourinho and his coaching staff are reportedly expected to assess Barcelona’s performance as they finalise their preparations. The observations could help Madrid identify potential weaknesses and refine their tactical plan, although Barcelona’s eventual lineup will depend on the fitness of their injured players.

The outcome of the PSG match could therefore offer useful clues about Barcelona’s readiness for the Clasico, with both teams preparing for a crucial encounter that could have significant implications for their season.
