not bad...
Anyway, I don't think we've been linked with either.
But I think United could do a lot worse than look at Arshavin to replace Ronaldo, not quite the same position or style but in terms of creativity he'd be a massive asset if he could fit in.
And also Pavlyuchenko, he runs his arse off, is tall and can score with both feet. He's a bit inefficient I think at the moment, misses a few chances but I think he has the potential to be a very good all round striker.
Both would be quite cheap I'd expect, but I don't see us going for either.
