Drogba another Grosso? You make it sound as if Grosso used to be a world class player and he plays bad now only because he lost motivation.
I'll explain it for you alen.
Drogba, is a champion, one of the top 3 strikers in the world, no doubt. However, he is close to 33 years old and for a striker with his characteristics, he's past his best and soon serious decline will follow.
But mostly, he won much at chelsea, played many championsleague games including final and semi finals. Will he be motivated when he comes here ?
Grosso was a good player when he went to lyon, when he won the world cup. when he returned to italy for juventus, he was past his best and in serious decline, and totally lost his determination, motivation and ambition he once had.
The reason i compared to drogba, is because i wonder if drogba wouldnt go the same way, playing without motivation and determination, beeing a fraction of his former self because he'd play at a lower reputation team thats not in the championsleague.
