Arsenal's bad form in Europe in recent times has allowed newcomers Leicester City to improve their record in the last few years.
Arsenal have not seen the Champions League quarter-finals in six years, while Leicester, having beaten Sevilla 3-2 on aggregate, have made it through on their first season.
It is not just at continental level that the Foxes are creeping up on the Gunners, as Arsenal have not got their hands on the Premier League since 2004. Leicester famously won the trophy last year.
