The former Barcelona boss hasn't been able to return to a UEFA Champions League final since 2011, being eliminated by Chelsea, Real Madrid, Barcelona & Atlético.

No UEFA Champions League glory for Pep Guardiola, at least for the past four years.

As the Catalan coach prepares to join Manchester City next summer, his project to win the coveted European tournament once more will have to wait at least a year, since Bayern Munich wasn't able to eliminate a tough Atlético Madrid side.

Despite winning the second leg of the series against Los Colchoneros, Guardiola & Co. will have to watch the tournament's final on their flat screen, since an away goal by Antoine Griezmann sent Die Roten packing. 

To make matters worse for Pep, this has been the fourth straight time in which his teams haven't been able to make it to the tournament's final. In 2012, Chelsea eliminated Barcelona and went on to win the trophy. After taking a sabatical, Real Madrid ousted Bayern with a 5-0 aggregate, humiliating them at Allianz Arena with a 4-0 score line. Last year, Barcelona eliminated the Bavarians, and this year, Atlético kicked them out of the competition with their tough defensive style.

Fans didn't forget how Guardiola arrived to Munich, and how he will leave for another challenge without winning another UCL trophy. Here are the best reactions from fans and experts.
