5. PSV Eindhoven
PSV Eindhoven may be well off the radar with regards to the Champions League, failing to qualify for the competition since 2008.
But prior to their demise they were regulars in the competition, appearing in 12 different seasons.
They only made it out of the group stage in three of those campaigns, with their best performance seeing them reach the semi-finals in 2005.
PSV have won a European Cup, however, taking home to defunct trophy in 1988.
