Shelvey is quality lol, he's only 19. Was banging in goals for blackpool at centre mid. Henderson is a maybe, we'll see next season if he comes good. Lucas was **** for his first 2-3 seasons at liverpool.
No one said he's as good as iniesta in the arsenal thread from what I read. Also mario gomez.
giroud or dzeko?
Most Liverpool players turn out to be pretty bad, so it wouldn't surprise me if they did.
It may have been in the United thread, but some fool who supports Arsenal put Santi Cazorla in the same bracket as Xavi and Iniesta. Furthermore, some Arsenal fans think Cazorla can make Arsenal a side that will challenge for the title this year. He's a very good player, but it will take time.
I haven't seen too much of Giroud, so I'd say Dzeko. :/
I'll probably let someone else answer your comparison.
