Crystal Palace are taking part in European competition for the first time this season and this result will add to the concern about how the squad will deal with the extra midweek games.
Arsenal are a challenge for anyone and the Palace players visibly tired as the match reached the latter stages.
Oliver Glasner will have to think how best to rotate his players while the fixture schedule for his team is so congested.
Palace are now without a win in four games in all competitions but it has still been a solid start for them in the Premier League this season, with 13 points from nine games.
