Petr Cech recently announced he will retire from professional football at the end of the season, the Czech goalkeeper - now 36 - has had a trophy-laden career predominantly in the Premier League with Chelsea and current club Arsenal.
Cech currently holds the record for the most Premier League clean-sheets with 202 out of the 443 Premier League games the Czech has featured in.
Domestically the 6 ft 5 'keeper has seen a great amount of success, accumulating a total of four Premier League titles and five FA Cups.
Cech also managed to win silverware at Chelsea in European competitions, with the Europa League going to west London in 2013 under controversial boss Rafa Benitez.
Chelsea managed to overcome Benfica in the final 2-1.
The year before saw the biggest triumph of Cech's illustrious career though as his Chelsea side managed to edge out Bayern Munich in the 2012 UEFA Champions League final.
Cech proved to be the hero as the game went beyond extra-time to a nerve-wrecking penalty shootout, in which Chelsea won 4-3.
The former Chelsea number one impressively went the right way for every single penalty, managing to save Ivica Olic and Bastian Schweinsteiger's efforts.
This was after Cech had already saved Arjen Robben's penalty during extra-time.
In an interview with COPA90, Cech has uncovered how he prepared for a potential penalty shootout against the German giants.
And quite frankly, the amount of time that went into it is staggering.
"The video of Bayern penalties lasted two hours and 43 minutes. The game was played in 2012 and we had every penalty of each of the squad since 2007.
"We did it as a goalkeeper group, it was me, Hilario, Ross Turnbull and even Jamal Blackman. We each had a video, so each went through it on our own and made notes," Cech added.
"And when the game was approaching we had a meeting together with everybody's notes and then we watched it again.
"I've seen it about three times, so it was probably more like eight hours."
That is the equivalent of travelling from London to Glasgow or watching the first two Lord of the Rings films with 17 minutes to spare.
Cech believes that it was the work he put in beforehand that allowed him to perform so well in the shootout.
"It might have been a coincidence I don't know, but after watching all of these videos I don't think it was a coincidence."
