Shevchenko wasn't a flop mate lol, was absolutely amazing in Italy which is definitely outside of Ukraine, by the time he went England he was badly faded hence Milan letting him go so easily
Rebrov was never as good as he looked when playing with Shevchenko so was a bad buy and could list a whole list of players who flopped at spurs/West Ham from every country
Arshavin wasn't by any means a flop - just wasn't as good as we thought he would be after he bummed us in Europe, but for the money paid he didn't exactly do bad for Arsenal. Smertin was bought by the owner not the manager and never really got a look in
