I've never paid any great attention to Willian.
I see it mentioned that he would be viewed as a replacement for Arshavin.
What would he provide that Arshavin doesn't?
He's behind him in terms of assists and goals scored but perhaps he'd be more consistent?
Plus he has that extra gear and surge of pace that Arshavin seems to have lost.
It's been reported that Shakhtar value him in the region of £22 million which the way things are going seems about average for a player with "potential", proven first team profile coupled with technical ability, Brazilian nationality and CL experience.
Unless of course we're talking about Denilson.
