After missing the penalty that allowed Real Madrid to triumph over Atletico Madrid in the Champions League final Saturday, Atletico fullback Juanfran was so sad he wrote an open letter to Atleti fans promising the future will be better.

(Side note: the moment when Juanfran ran over to the Atleti fans to beg forgiveness for the penalty miss and they gave him a standing ovation was beautiful.)

Here's the letter in full:

Hello Atléticos, 

Y'all already know who won. We already told you in the headline, so here's some things from the Champions League final. But first, the highlights.

Here's Sergio Ramos's goal.

Looking to kill time at work? Going to a Champions League party and need to get in the know? Are you anxiously awaiting the Madrid Derby in the UCL Final and need every bit of content surrounding the match? We got you covered on all fronts.

Our esteemed staff here at The18 has given responses to the biggest questions ahead of the Champions League final between Atletico Madrid and Real Madrid. Call us idiots, call us geniuses, just be ready for takes so hot that they'll leave you wishing you were dining with the Night's King from Game of Thrones. Let's meet the lads.

Do you remember the first time soccer blew your mind? For me, it was Ronaldinho. Not even a specific clip, just Ronaldinho in general. The more and more I watched of him the more I realized that my understanding of soccer was so timidly different than what was really possible that it practically hurt; I needed to watch more highlights, and I swear I got high from them. 

I thought the days of Ronaldinho blowing my mind were done, but this one goal, this legendary goal that many of you have already seen before, has come back to do it again:

Gareth Bale has stated that he believes no one on Atletico Madrid’s roster could make the starting XI of Real Madrid ahead of Real and Atletico’s clash in the Champions League final on Saturday.

Javier Mascherano is reportedly in talks with Juventus regarding a potential summer transfer from Barcelona.

When former Marine Jake Sully first entered his Na’vi-human hybrid in the 2009 sci-fi film Avatar, he couldn’t control his excitement — he delighted in his newfound athleticism while embracing the pastoral beauty of the planet Pandora. It was a scientific breakthrough, the likes of which hadn't been replicated up until yesterday. Yesterday, Neymar had his own Jake Sully moment.

Cristiano Ronaldo limped out of Real Madrid training Tuesday and may not be fully fit for Saturday's Champions League final against crosstown rivals Atletico Madrid.

The San Siro in Milan will play host to the 2016 Champions League final as Atletico Madrid take on local rivals Real Madrid. It is a rematch of the final from two seasons ago, which Real won 4-1 in extra time, despite being down 1-0 for most of the match. This will be only the second time that a European Cup final will be contested by two clubs from the same city.  

Now that the pomp and circumstance of Barcelona’s Copa del Rey win over Sevilla has subsided, Lionel Messi has posted a message to Facebook that speaks to his appreciation of how he and his teammates suffered and persevered in order to accomplish their goals.
