"It's a good time to play Madrid," Hamann told Genting Casino. "I don't think Mbappe has improved them. I think they've got too many stars, or too many players who want to shine, and not enough players who make others better. Somebody's got to do the work.
"The player who's probably suffered the most after the arrival of Mbappe is [Jude] Bellingham. He scored a hatful of goals before Christmas last season. He played pretty much as a centre forward because they didn’t have one, and now he’s got to do some dirty work, because you can’t have four players not defending - three is probably too much.
"Mbappe and Vini don’t do it, Rodrygo sometimes does. It can't function. You can't defend with six or seven players. It's impossible. You might beat teams in La Liga, but you won’t beat the best teams in Europe.
"Obviously, they've got great individual quality, but I think there's a lot of question marks about the team. I don't see them defending the title."
