Roethlisberger was in London to promote the Steelers' Sept. 29 game against the Minnesota Vikings, which will be played at Wembley Stadium. The Steelers quarterback was asked by the London media what motivates him and his response was tweeted by Steelers public relations director Burt Lauten.

Bradshaw emerged victorious in all his title-game appearances during his 14 seasons with the franchise. Roethlisberger has two rings in his nine seasons with the Steelers, losing in his last appearance as Pittsburgh fell to the Green Bay Packers in Super Bowl XLV.
Roethlisberger, 31, needs three more Super Bowl wins to surpass Bradshaw, who became the first quarterback to win four Super Bowls.
Roethlisberger broke Bradshaw's Steelers all-time passing yards record last season and finished the season with 29,844 yards in his career. He can own two more of Bradshaw's records this year: career pass attempts (needs 140 more) and touchdown passes (22 more).
While in London, Roethlisberger participated in a fan forum and also visited some of the city's famous landmarks, including the Big Ben clock tower, with which he shares a nickname.
Roethlisberger will travel to Ireland later this week to visit with Steelers chairman Dan Rooney, who is the former United States ambassador to the country. The quarterback will handle the coin toss at the flag football game Rooney annually hosts on July 4.
"I got to go to the Ambassador's residence last year and see what he does there, but it will be great to go back," Roethlisberger told the team's website. "Plus we get to see the game he puts on for July 4 and I will make sure I do a good job flipping the coin."
