The former Arsenal and Chelsea footballer has already retired, after losing the UEFA Europa League with the Gunners.
Goalkeeper Petr Cech started playing professionally in 1999 with Chmel Blsany.
In 2001 he moved to Sparta Prague and the next year to Rennes.
But it was in 2004 when he went to the English Premier League, joining Chelsea.
And in 2015 he moved to Arsenal, retiring at the end of the season.
“I think everything goes down to work,” Cech told the Gunners’ official website.
“You can have as much talent as you want, you can have so many opportunities from people around you, but if you don’t work hard and you are not prepared to take them, your career can take a completely wrong direction or never kick off.”
He explained: “I will say everything goes down to work and love for the game.”
“You also need to keep challenging yourself and that you can learn at any age. People sometimes say, ‘He is too old to learn’. No, it is not true.”
“If you keep challenging yourself and you keep trying to get better, this is how you actually improve yourself and get better,” he added.
“I can tell you that at 37 years of age, at the end of my career I’m still learning and still improving every day because I actually work every day to get better.”
“I think this is the only way to have a successful career and actually make the most of it,” he said.
“As best as you can be, this is actually the best advantage and the best way to have a great career.”
PETR DOES IT AGAIN! 💪
