Arsenal's training today notably saw the absence of both Kai Havertz and Martin Ødegaard, despite previous expectations from coach Mikel Arteta that they might be fit for tomorrow's match against Atletico Madrid in the second leg of the Champions League semi-final.

According to the data, the absence of the duo raises doubts about their readiness for the crucial match, especially since Ødegaard is considered a key player in playmaking, while Havertz is an important option in the forward line.

The duo, Jurrien Timber and Mikel Merino, continued to miss the team's training sessions due to their ongoing injuries that have kept them off the field for several weeks, reducing coach Arteta's options for rotation and substitution in the upcoming match.

These absences place Arsenal in a significant challenge ahead of a crucial home match, as the team needs to be in the best possible form against Atletico Madrid in the battle for a spot in the Champions League final.
