Arsenal are hopeful that a spate of illnesses that have spread through the squad will have cleared up in time for their Premier League clash with Fulham.
Kieran Tierney was unable to travel to the Gunners' Europa League first leg clash with Sporting CP on Thursday due to sickness, while Martin Odegaard had to drop out of the squad at the last minute despite having travelled to Lisbon. Fabio Vieira was also understood to be dealing with a sore throat in the build up to the match, but was able to play the full 90 minutes at Estadio Jose Alvalade and registered an assist for William Saliba's opener in the 2-2 draw.
With a crucial match against Fulham coming up this weekend Arsenal will of course be keen to prevent any illnesses spreading among the group. Speaking ahead of the match, manager Mikel Arteta admitted he was hopeful this could be achieved.
