Having won six Grand Slam titles and attained the number 1 ranking in professional tennis, Boris Becker is no doubt one of the best tennis players of all-time. And Becker has kept his competitive fire going through the game of poker as he recently attended the 2011 World Series of Poker Europe.

The Huffington Post, which is a UK news site, caught up with the German at the 2011 WSOPE, and inquired about his deep interest in poker. Becker told Huffington that there are many similarities between poker and tennis as he said, "Mentally, it requires very much a similar approach in terms of discipline, endurance and concentration." 

Becker continued his thought by adding, "Poker is actually a very slow game, which requires patience - just as when you win a Grand Slam, it takes two weeks and years of preparation, not just one good ace, but seven good matches. Similarly, it takes five excellent days of poker to win a tournament." 

Unfortunately for Boris Becker, he didn't cash in the 2011 WSOPE Main Event, but that's not going to stop him from continuing to play poker. In fact, he'd also like to see some of his fellow tennis opponents out on the tables as he said, "I'm convinced Roger Federer would make a good poker player, because he has a god-given talent to play tennis and he's very humble and casual. I'd love to have John McEnroe on the poker table, for the excitement and the noise. Agassi and Sampras are both good players, I know."

Until these players do get on the poker tables, Becker will continue to carry the torch for his fellow tennis players. So far, he's cashed in four live poker tournaments, and they're listed below:

2011 EPT Barcelona Main Event - 97th place, $11,525

2009 EPT Prague NLHE - 32nd, $1,723

2009 Five Star World Poker Classic Main Event - 40th, $40,855

2008 EPT Grand Final NLHE - 7th, $18,672
