It might be impressive (if I was closer I might have appreciated the skill involved). But half time at a football match is not the place to celebrate worldwide (or even UK) cultural events. No-one is interested, especially when everyone realises that it is a cynical attempt to appeal to a merchandise buying market half way around the world. It certainly hasn't been chosen because someone is of the honest belief that the people in the stadium would really like to see a festival of dance at half time.
No-one is really interested in the stupid games or the football based guests that they have on at half time either - but at least they stand a better chance of being of interest to some, given they are somewhat related to the reason that everyone is there or actually involve members of the crowd.
I don't recall half time celebrations for Chinese New Year in the past but I'll take your word for it.
