Osi Umenyiora knows what it takes to beat Tom Brady in a Super Bowl: pressure.
The London-born defensive end won two Super Bowl rings with the New York Giants, and both victories came against Brady and the New England Patriots.
Brady – now of the Tampa Bay Buccaneers – will play in his 10th Super Bowl on Sunday trying to win his seventh ring, with defending champions the Kansas City Chiefs in the way.
The Giants caused a huge upset when they beat the Patriots in Super Bowl XLII in 2008, scoring 14 fourth-quarter points in a 17-14 win that ended New England's bid for a perfect season.
Umenyiora recorded four tackles in the game as New York focused on getting in Brady's face.
Speaking ahead of this weekend's Super Bowl LV in Tampa, Umenyiora said: "We know this is the greatest quarterback of all time, but at the time we were playing, I don't think you could say he was the greatest quarterback of all time.
"To us, he was just a really good quarterback. The thing we noticed really bothered him wasn't so much pressure off the edges because he was very nimble in the pocket, it was pressure up the middle...
There is no question Brady is a different player now to the one Umenyiora went head-to-head with, but he said if he was playing against the 43-year-old on Sunday, his approach would be little different.
"We'd be even more ferocious," he said. "I think maybe because he might not be quite as nimble as he is in the pocket as he is older, even though he's not playing like that, he's playing lights out...
"He's no different than any other quarterback. Whenever you get pressure on him and you're able to get people up into space, things aren't going to be so good for him."
