That explains it. But the O2 is a great stadium. And when I was there it was sold out or very near so. Admittedly, that was for a Slavia/Sparta rivalry game, but it seemed the games Lev played there in the playoffs were pretty near capacity as well. So, it seems there is a market for larger stadiums. I was only in Tipsport for a couple of Lev games, which drew well, but not to capacity. I would assume Sparta would draw better there. I also learned never wear a Slavia jersey to even a Lev game at Tipsort (I had come straight from the O2 for the Slavia/Sparta game so didn't have time to stop at the hotel and change into my Lev jersey). That does not go over well.
