I'd say more like definitely.
Anyhow, NFL games between random teams sell out at Wembley and could probably sell 150,000 tickets upwards per game if it were possible. I don't think I've ever met a serious NFL fan here, either.
I know it's a different format and novelty involved there but it's an indication of what bringing a famous brand in for a limited period of time can do. Those two teams stole a march on everyone in the football world, and Barfa have done well to claw ground back (thanks to their amazing success + Messi).
