Who better to have a quick chat with one of the biggest names in America's biggest game - 49ers quarterback Colin Kaepernick, who led his team to the Super Bowl last season, and has helped 49ers win five matches on the trot this term, for a 5-2 winning record so far.
The 49ers are in London to take on Jacksonville Jaguars in NFL Game 8 at Wembley Stadium on Sunday.
Here's what happened when Harry - a fan of 49ers' rivals the New England Patriots - met Colin Kaepernick...
Harry: So how are you finding it over here in the UK?
Colin: "We’re having a great time out here. It’s my first time leaving the country, so happy to be here already."
Harry: Are you looking forward to playing at Wembley?
Colin: "Yes, excited. A lot of great teams have played there so to step on the same field as them will be amazing."
Harry: I’m a Patriots fan so I’m talking to the enemy right now! How do you think you’ll do this season, because you were unlucky to lose in the Super Bowl last season...
Colin (laughing): "Well hopefully we will finish well. We had a little bit of a shaky start but we’ve strung a few wins together and hopefully we can keep that rolling."
Harry: You’ve got a great team and I’m sure you’ll have a great season. It’s been a pleasure to meet you and maybe one day we can run some plays together!
Colin: "Sure, and you can show me a little bit of soccer too! Great to meet you."
Meanwhile, Colin added that it was a pleasure for him and the 49ers to join up with the Tottenham Hotspur Foundation to put students from the nearby Nightingale Academy through their paces.
49ers players rubbed shoulders with members of our first team squad including our American goalkeeper Brad Friedel, Mousa Dembele, Lewis Holtby, Christian Eriksen and our keenest NFL fans, Harry and Jan Vertonghen at five stations of football and American Football skills.
One station had students being taught how to throw an American Football by Colin!
Asked about the work of the respective Foundations at Spurs and the 49ers, Colin said: "It's very important, epecially when these Foundations are for the kids.
"It's something we want to be involved with and help with. A lot of us were like these kids, coming out to camps, waking up to pray about doing what we're doing now, so anytime we can give back to the children, we want to."
