Arsenal manager Mikel Arteta has admitted he does not know when some of his key players will return after Declan Rice, Bukayo Saka, Martin Odegaard, Jurrien Timber and Riccardo Calafiori all missed training ahead of the Champions League second leg against Sporting CP.
Arteta has been left sweating over the fitness of the key quintet ahead of a week that also includes a potentially season-defining match away at Manchester City in the Premier League.
