Arsenal supporters can be forgiven for avoiding the Champions League like the plague this season. The Gunners had qualification for Europe's top competition in their hands, but defeats to fierce rivals Tottenham and then Newcastle in the last three games of last season's Premier League campaign ended their hopes.
They relinquished their place back at the top table to north London rivals Tottenham, who bested them by two points in the end. And Tottenham will begin their Champions League quest on Wednesday night, with Arsenal waiting to play in the Europa League on Thursday.
Gunners fans would happily forget about the Champions League and concentrate on the Europa League and the Premier League, where they sit top of the table after the first six matches. But there may be a reason - or five - to watch their biggest rivals in action tonight.
