Arsenal analysis: Martinelli stars for much-changed Gunners

Gabriel Martinelli scored a hat-trick as a heavily rotated Arsenal side secured an away win, with Mikel Merino captaining a team that included several squad players and the returning Kai Havertz.

Gabriel Martinelli produced a hat-trick while Arsenal named a heavily rotated side in an away match. The season has been mixed for Martinelli; he faced criticism earlier in the week over an altercation with injured Liverpool defender Conor Bradley. He has lost a regular starting place in the Premier League but has scored in Arsenal's opening four Champions League games. Manager Mikel Arteta used the club's increased depth after eight summer signings to make ten changes. Key facts: - Martinelli scored his first hat-trick for Arsenal in the match. - He had been criticised for an altercation with injured Liverpool defender Conor Bradley during the week. - Arteta made ten changes to the side; Gabriel Magalhaes was the only player retained from the team that drew with Liverpool. - The lineup included captain Mikel Merino, Noni Madueke and Eberechi Eze, and saw Kai Havertz return after a knee injury. - This was the first of four away games in four different competitions for Arsenal this season. Summary: Arsenal used squad depth to give minutes to non-regular starters while achieving a positive result, and Martinelli’s hat-trick added to his strong run in European fixtures. Mikel Merino stood out in a deeper midfield role and Kai Havertz made his first appearance since a season-opening knee injury. The club begins a run of four successive away matches across different competitions.
