Uefa championship pochettino affirms wembley spell

I think there may be a bit of a misunderstanding here!

It seems like you're trying to create a sentence, but it's not quite grammatically correct or coherent. Let me help you break it down:

• "UEFA Championship" is a competition, not a person or a place, so it can't "affirm" anything.
• "Pochettino" is a person, Mauricio Pochettino, a former football manager, but he can't "affirm" a place like "Wembley" either.
• "Wembley" is a stadium in London, England, but it's not a person or a thing that can be "affirmed" either.

If you meant to say something else, please feel free to rephrase or provide more context, and I'll do my best to help you out!
