Arsenal will be wary of being handed potentially a major blow ahead of a crucial match in the Champions League.

The Gunners will take on Slavia Praha in their fourth league phase fixture in the competition on Tuesday night as they look to maintain their 100 percent start.

Mikel Arteta's side have won all three of their opening matches in the Champions League this season, all without conceding a single goal, with victories against Atletico Madrid, Olympiacos and Athletic Club.

The fixture against Slavia Praha will be Arsenal's last European match before the November international break, but the Gunners will be mindful of a potential suspension concern.

Declan Rice has already received two yellow cards in the Champions League this season, which came in the wins over Olympiacos and Athletic Club, and another would see the England international handed a one-match suspension.

If Rice were to pick up a booking during the clash against Slavia Praha, he would then miss Arsenal's next Champions League clash against Bayern Munich on November 26 at the Emirates...
