Arsenal took a clear and collective decision not to invest last month. That decision now appears set to haunt them

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.

David: This finishes Arsenal's season. The die was cast in the summer when rather than adding depth to the squad, it was weakened. They had another chance in January and did not take it. We will encounter more and more injuries as players are overplayed. I will be surprised if we finish in the top four.
