Arsenal and defending champions Barcelona played to a goalless first half in the Women's Champions League final in Lisbon on Saturday, with both sides creating opportunities in a tightly contested match.

The Gunners, appearing in their first Champions League final since 2007, had a moment of celebration when Barcelona's Irene Paredes appeared to score an own goal in the 22nd minute. However, the potential breakthrough was ruled out after VAR review determined Arsenal's Chloe Kelly was offside in the build-up.

Barcelona, who entered the match as heavy favorites after dismantling Wolfsburg and Chelsea in previous rounds, threatened through Aitana Bonmati, while Arsenal's Frida Maanum forced a strong save from Barcelona goalkeeper Cata Coll with a long-range effort.

Arsenal goalkeeper Daphne Van Domselaar, who was declared fit to start the crucial match, made several important interventions to keep the scoreline level, including a confident punch to clear a dangerous Barcelona attack.

The match is being played in challenging conditions, with temperatures reaching 28 degrees Celsius in Lisbon. The heat appears to be taking a toll on players, particularly Arsenal's squad who are less accustomed to such conditions compared to their Spanish opponents.

Arsenal captain Leah Williamson, who was a mascot when the Gunners last reached the final 18 years ago, has been solid in defense alongside her teammates as they attempt to become the first English team to win the trophy since their own triumph in 2007.

Barcelona, seeking to defend their title, fielded a formidable lineup including stars Alexia Putellas, Caroline Graham Hansen, and Bonmati, while Arsenal's attack is led by England international Alessia Russo, who has found excellent form under manager Renee Slegers.

The atmosphere at the sold-out stadium has been electric, with approximately 5,000 Arsenal supporters in attendance compared to an estimated 30,000 Barcelona fans who have made the journey to Portugal.

The second half promises to be equally competitive as both teams push for the goal that could decide the prestigious European trophy.
