Barcelona will face Real Madrid in the final El Clasico of the season on Sunday at the Olympic Stadium, aiming to extend their La Liga lead to seven points. After a disappointing Champions League exit, Real seeks to revive their title defense, needing a win to close the gap to one point, while Barcelona hopes to secure their third trophy of the season after winning the Copa del Rey and Super Cup. Both teams have critical matches ahead, with Barcelona’s squad facing injury challenges and Real considering lineup changes, including a potential start for young midfielder Arda Guler.
