Kai Havertz will undergo surgery on his torn hamstring in the coming days, Arsenal have announced, with his rehabilitation program due to carry through into the 2025-26 preseason. Havertz suffered the injury at his side's warm-weather training camp in Dubai last week but the full extent of the injury only became apparent on returning to London earlier this week.

Trossard led the line away to Girona in the Champions League when Havertz was rested last month and played centrally just off the German during a run of games last autumn, when Arsenal shifted to a 4-2-2-2 system to accommodate Martin Odegaard’s absence from midfield.

Arsenal’s Premier League title challenge has been dealt a blow after forward Kai Havertz was ruled out for the season with a hamstring injury.
