Spain and Barca would've won those trophies without him, easily.
Cesc didn't always deliver though, he had his fair share of big-game failures. He went years without making laying a glove on Chelsea, for example. Not all his fault of course but lets not rewrite history because he gave a nice interview.
You can't just compare Cesc at his best, with Özil in his quieter seasons. The debate is about the two in their primes.
Let Jury have his fun.
