France is the favourites, but then so were they in 2020. Mbappe will want to deliver a EURO before he leaves France, of course. Probably the last tournament we'll see Griezmann operate at a world-class-ish level as well.
I think Spain can surprise people. Not a fan of Southgate's squad nor do I think he'll use it properly (incoming Foden out wide again). Germany looking good for sure. Kroos can have a fairy-tale ending to his career with both UCL and EURO (the last thing he hasn't won).
