Arsenal kicked off their Champions League campaign with a strong victory against Athletic Club, thanks to impactful substitutions made by manager Mikel Arteta. Gabriel Martinelli and Leandro Trossard, who came off the bench, played pivotal roles in securing the win.

Cagey First Half

The match at San Mames started slowly, with both teams struggling to create clear chances in the first half. The home crowd, eager to witness European football after an 11-year wait, filled the stadium with energy. Athletic Club had a solid home record in the previous season's Europa League, winning six of their seven matches, and they began the game with more possession. However, Arsenal's defense, led by David Raya, held firm, preventing any significant threats.

Despite a lack of scoring opportunities, Arsenal's Ebere Eze came close to breaking the deadlock, only to be thwarted by a crucial block from Aitor Parades. Viktor Gyokeres also made an impact, testing Athletic's goalkeeper Unai Simon with a shot after a strong run down the left flank. As the half progressed, Athletic Club's Dani Viviane took advantage of a gap in Arsenal's defense, but his low shot missed the target. Alex Berenguer then had a chance to score from a corner, but his header went wide, leaving the teams level at halftime.

Super Subs

The second half saw Arsenal increase their attacking threat, with Gyokeres playing a key role in creating opportunities. His hold-up play allowed Noni Madueke to break through, forcing Simon into a save. The momentum shifted when Martinelli and Trossard were introduced, with Martinelli scoring just 36 seconds after coming on. He received a pass from Trossard and made a 50-yard run before finding the back of the net. Trossard then capped off the victory by scoring in the 84th minute, assisted by Martinelli.

This victory marked a historic moment for Arsenal, as they became the first team in European Cup history to win six consecutive matches against Spanish clubs. Martinelli's performance also highlighted his knack for scoring long-range goals in Spain, having previously netted against Sevilla and Real Madrid.

With this win, Arsenal's Champions League campaign is off to an excellent start, showcasing the depth and talent within their squad.
