Arsenal’s 2-0 victory over Athletic Club in their Champions League opener showcased the squad’s depth and resilience, but it also sparked discussions about Mikel Arteta’s tactical decisions as the Gunners prepare to face Manchester City on Sunday at the Emirates Stadium. Late goals from substitutes Gabriel Martinelli and Leandro Trossard secured three points in Bilbao, while new signing Cristhian Mosquera earned widespread praise for his composed performance. However, Arteta’s choice to substitute striker Viktor Gyokeres drew criticism from an Arsenal legend, highlighting the challenges the manager faces in balancing his squad.

Cristhian Mosquera’s Impressive Champions League Debut
Arsenal’s £13million summer signing from Valencia, Cristhian Mosquera, made a strong impression in his Champions League debut at San Mames. The 21-year-old defender stepped in for William Saliba, forming a solid partnership with Gabriel Magalhaes. Mosquera’s composure, both in duels and on the ball, earned high praise from teammate Jurrien Timber, who told TNT Sports, “He does amazing. Still so young, the way he comes in, it looks so easy for him, winning his duels and on the ball as well. It is great to have him next to me, and I think he has a bright future ahead.”
Arsenal legend Martin Keown echoed Timber’s sentiments, noting, “This fella, mobile, quick, strong, there’s a lot more to come. He’s put in some really good performances.” Mosquera’s seamless integration into the squad underlines Arteta’s trust in the young defender, who has quickly become a reliable option in Arsenal’s backline.
Arteta’s Midfield Dilemma Ahead of Manchester City Clash
Despite the victory, Arsenal’s performance against Athletic Club exposed areas for improvement, particularly in midfield. Arteta opted for a trio of Martin Zubimendi, Declan Rice, and Mikel Merino in the Champions League curtain-raiser, a combination that also started in Arsenal’s recent defeat to Liverpool. According to Sky Sports, Rice and Merino have only won one of their nine Premier League games as a midfield partnership, with Arsenal’s 4-0 victory over Ipswich being the outlier. This statistic raises questions about the balance of Arsenal’s midfield as they prepare to face a formidable Manchester City side.
With captain Martin Odegaard doubtful for Sunday’s match due to a shoulder injury, Arteta faces a critical decision. Youngster Ethan Nwaneri, who replaced Odegaard early in Arsenal’s recent win over Forest, remained on the bench against Athletic. Meanwhile, Eberechi Eze, who has thrived as a number 10 for Crystal Palace, could offer a more attacking option if deployed in a creative role. With Bukayo Saka sidelined by a hamstring injury, Arteta may need to rethink his approach to unlock Arsenal’s attacking potential against City.
Viktor Gyokeres Substitution Sparks Debate
One of Arteta’s tactical decisions during the Athletic match drew scrutiny from former Arsenal star Perry Groves. In the 65th minute, with the game still goalless, Arteta substituted striker Viktor Gyokeres, who had sustained a cut to the back of his head, for Leandro Trossard. Groves, commentating for talkSPORT, questioned the move, saying, “It’s just strange, I don’t know, Mikel Arteta has obviously got his reasons. But you’ve got your centre-forward on the pitch who has been a threat in behind all game. He’s holding the ball up, Arsenal are starting to exert a little bit of pressure. If you’re a centre-forward, if you’re Gyokeres, you’d be devastated coming off.”
Groves argued that Gyokeres, who had been a constant threat, would have been disappointed to leave the pitch at a moment when Arsenal were gaining momentum. However, Arteta’s substitutions proved decisive. Less than a minute after replacing Eze, Gabriel Martinelli broke the deadlock, and Trossard sealed the win with a deflected shot in the closing stages. While the result vindicated Arteta’s choices, the debate over Gyokeres’ withdrawal highlights the fine margins in high-stakes matches.
Looking Ahead to Manchester City
As Arsenal shift their focus to Sunday’s clash with Manchester City, Arteta must navigate a series of challenges. The depth of his squad, exemplified by Mosquera’s assured performance and the impact of substitutes like Martinelli and Trossard, gives Arsenal reason for optimism. However, injuries to key players like Odegaard and Saka, combined with questions over the midfield balance, present significant hurdles. Arteta’s ability to make bold tactical decisions, as demonstrated in Bilbao, will be crucial as the Gunners aim to secure a statement victory against the Premier League champions.
