Winning the UEFA Champions League is already one of the hardest achievements in football, but lifting the trophy without suffering a single defeat throughout the campaign is an even rarer feat.
Only a few number of teams have successfully conquered Europe over the years, leaving their mark on football history with outstanding performances from beginning to end.
If Arsenal wins the UCL later this month, they could be added to the elite group. The Gunners are now in the finals after defeating Atletico Madrid in the semis of the UEFA Champions league on Tuesday.
