Arsenal manager Mikel Arteta believes the accumulation of long-term injuries experienced by some clubs is an “accident waiting to happen” because of the increased demands on players in a busy soccer calendar.

Mikel Arteta has described Kai Havertz's hamstring injury as "an accident waiting to happen" and issued a rallying cry to his players to show "what you're made of" in his absence. The 25-year-old will undergo surgery and miss the rest of the season after sustaining the problem while defending a set-piece during the club's winter training break in Dubai earlier this week.

Arsenal's injury worries have been exacerbated in recent days after losing Kai Havertz to a season-ending hamstring tear.
