arsenal want to buy nani from man u for 20m ( which we dont need him ) and could replace him with nani.
who is better? 

Watching the vids from Golden, I am struck by how beautiful that 2nd goal by Utd against City was. Why aren't Utd playing like that all the time? Not even Barca can claim a better one.

I remember when CR7 left United then Nani tried all his tricks so Nani was a CR7-wannabe but know he got his own playstyle.. and that makes him better..

nani sometimes can go haywire but on his best day he cud go past any defenders in the world .But i think walcott is more about pace rather than dribbling .Obviously both of em have their own specialty 

You can't compare them. Walcott>Nani. I think about Walcott vs Bale. Look at their speed!
