​Argentina and ​Barcelona superstar, ​Lionel Messi is widely considered to be one of the greatest players in the world, if not the greatest, with the striker winning a plethora of professional and personal honours during his career.

The 32-year-old who has five Ballon d'Or awards to his name created another piece of history way back in 2012 when netted 91 goals in the calendar year, thereby breaking the record of 85 goals set by ​Bayern Munich legend, Gerd Muller which he set in 1972.

After breaking that record, Messi gifted Muller a signed shirt that read: "For Gerd Müller / My respect and admiration / A hug." This was later gifted to Bayern by Muller which to this day remains the only piece of memorabilia, non-related to the club in the entire stadium.

The shirt was accompanied by a letter written by then Barcelona president, Sandro Rosell, which was titled, "recognition of the player and person that is Gerd Müller".

"The esteem and admiration our club feels for Bayern and it's fans is demonstrated once again in the historical tie between these two great players who have become sporting legends of our clubs," Rosell wrote in the letter.

This gesture between two legends of the sport just goes to show why both of them are loved by fans not only of their respective clubs but by everyone the world over.
