Players that Souness couldn't get to play for him - Robert, Bellamy, Kluivert, Dwight Yorke, Richard Dunne etc etc
As far as transfer targets go I think it is a combination of not wanting to play for Souness who does not have anything like the international reputation of Robson, the fact the club is always in the media for the wrong reasons, our lowly league position last season (likely to be even lower in the coming one), not being in Europe etc
It has always been harder to attract players to the North and you need a manager like Robson or Keegan, European football and to look like the club is going somewhere to make us stand out from the rest and attract people. At the moment it seems the only players who will come are the ones who are more money orientated i.e. we were the only ones prepared to match Parkers wages at Chelsea and to pay Emre the £60,000 a week he wanted.
