Isaan Khan of the Daily Mail reports that he understands Arsenal youngsters Ceadach O’Neill and Maalik Hashi will both be in the Gunners’ Champions League squad to face Lille on Tuesday night.

The Champions League games take place on the same day as the u19s’ UEFA Youth League matches against the same opposition, so there are often some hints in the u19 squad lists at players who may have received senior call-ups.

Indeed, neither O’Neill nor Hashi were named in the u19 squad on Tuesday morning, with Max Dowman and Marli Salmon also absent.

This won’t be 18-year-old O’Neill’s first call-up, as he was in the FA Cup squads to face Wigan Athletic and Southampton last season. But this will be the forward’s first appearance in a Champions League squad, and he’s still yet to make his competitive on-field debut.

As for fellow 18-year-old Hashi, this is the midfielder’s first senior call-up, likely as a response to Martin Zubimendi’s injury setback.

Dowman was always likely to be called up for the game, as he’s regularly made the Premier League benches this season, and the Champions League squads have even more bench spots available.

If Salmon is involved too, that’s probably another reaction to a recent injury, with Piero Hincapie spraining his ankle.
