Arsenal's open training sessions before the second leg of the Champions League quarter-final against Sporting Lisbon saw the absence of a large number of stars, most notably Declan Rice, along with Bukayo Saka, Martin Ødegaard, Jurrien Timber, and Riccardo Calafiori, amid growing concerns within the coaching staff.

The absence of Rice specifically caused the greatest concern, especially since he suffered a sprain after a bad landing during the Bournemouth match. Nevertheless, he has not been completely ruled out of the return leg, leaving the door open for the possibility of his participation in a crucial European match this week.

Coach Mikel Arteta's squad is suffering from a widespread injury crisis, which limits his options in midfield, especially with the continued absence of a natural replacement for player Rice. Several solutions are being considered, such as relying on Kai Havertz in midfield, or involving Leandro Trossard, in addition to the possibility of including Miles Lewis-Skelly, given the limited available options.

Arsenal is preparing for a crucial double-header this week, aiming to secure qualification against Sporting, before a strong Premier League clash against Manchester City on Sunday, in a match that could be decisive in the title race. Meanwhile, Arteta is awaiting further clarifications on the condition of Rice and the other injured players in the upcoming press conference.
