#3 Chelsea
The 2020-21 Champions League winners have had a fantastic time ever since Roman Abramovich took over club's ownership in 2003. Chelsea have enjoyed tremendous success under the ownership of the Russian and are not stopping any time soon.
The London club have so far played 187 matches in the Champions League yet have managed to win it twice. Chelsea may have found qualifying for the tournament difficult earlier on, but once they did, they made it count.
Amazingly, the Blues have scored 322 goals so far in the league. Chelsea have lost 10 times in the round of 16 despite playing much lesser games than any other team on this list. This speaks volumes of how good the club has been in getting beyond the knockout stages.
#2 Arsenal
If there was one thing that Arsenal fans would have very much longed for, it would be the Champions League trophy. The Gunners came agonizingly close to winning when they qualified for the finals of the 2005-06 season and lost 2-1 to FC Barcelona.
Since then, it has been a massive struggle for Arsenal to even qualify for the competition. The North London club have failed to play in the tournament ever since the 2016-17 season.
To date, the Gunners have participated in the Champions League 17 times and lost 13 times in the round of 16. Somehow, they have failed to capitalize in the knockout stages. It seems very uncertain as to when Arsenal will finally be able to win the tournament.
#1 Real Madrid
No other team has won the Champions League more times than Real Madrid. Los Blancos have been super dominant in the history of the tournament, having won it a record 13 times.
They have won it four times in the last decade and five times in the 21st century. With their star-studded squad, Real Madrid are always one of the strongest contenders to win it. The Spanish giants have so far played 458 matches, the most ever by any club in the competition.
With more games come more goals as has been the case with Real Madrid. Los Blancos have scored 1003 goals so far in the tournament yet have lost 13 times in the round of 16. They have managed to bounce back from a loss in a single leg and that is why they are the most successful in this competition.
