Bayern lifted the trophy at Wembley following their 2-1 defeat of Borussia Dortmund in an all-Bundesliga final.
Bayern are already looking particularly strong for next season with Mario Gotze joining the club in the summer and striker Robert Lewandowski also on his way to Bavaria from Dortmund, as The Independent reported.
But who will also be challenging the German champions in UEFA's elite tournament next season?
Read on to find out my selection. Who do you think will be in the last four in 2014?
It is going to be a fairly major surprise if the reigning champions are not involved in the closing stages of the tournament next season.
Bayern have been unstoppable this season. They had the Bundesliga title wrapped up at the start of April and even Barcelona had no answer as they lost 7-0 on aggregate to the German club in the Champions League semifinals.
Even the absence of Toni Kroos due to a groin injury could not stop the Bavarian juggernaut in the last two months of the campaign.
Former Barca coach Pep Guardiola will succeed Jupp Heynckes this summer, but the Spaniard would be unwise to tinker too much with the winning formula of this season.
Mario Gotze is already a confirmed addition to the squad from Borussia Dortmund, while striker Robert Lewandowski appears to be treading the same route.
Guardiola will also welcome back Kroos to his squad while Thomas Mueller remains an integral figure to the team.
Barcelona romped to the La Liga title, but the disappointment of the Champions League semifinal defeat to Bayern Munich will have hurt the Catalans.
The seven-goal aggregate loss was as upsetting as it was shocking as the Bundesliga champions served notice of their intent to take Barca's crown as the darlings of European football.
Injury to Lionel Messi did not help, but with the Argentina international back to full fitness for next season, the Camp Nou side will again be a formidable challenge for anyone.
It remains to be seen how Neymar gets on with the La Liga champions next year, but his presence will offer a new option to the team.
Further signings this summer will fuel Barcelona's ambition and desire to reclaim the trophy they last won in 2011.
The Blues fans are preparing to welcome back their hero after he left the club in 2007.
Mourinho endured a tumultuous season in charge of Real Madrid but still guided the team to the Champions League semifinals for the third successive season.
The Champions League and Mourinho have been synonymous with each other over the last 10 years, but the coach's bond with Chelsea is just as strong.
But Mourinho never progressed beyond the last four with Chelsea in his last stint at the club and will have a point to prove this time.
And with players such as Juan Mata in his squad and a foray into the transfer market this summer, Mourinho and the Europa League will be a force next season.
Juventus were unfortunate to be paired with a ruthless Bayern Munich in the Champions League quarterfinals this season.
After winning the Scudetto in successive seasons, Juventus coach Antonio Conte and the club are looking to prove themselves on the European stage again.
