The truth is, untill we watch them play and see how the fit into their new clubs, we won't be able to say whos signed the best players at the best value....
I'd not like to comment on which ones will suceed because the vast majority of the foriegn players who have come in, have the talent for sure to make big impacts for any of the clubs.
I personally think Newcastle have been pretty shrewd in the market, with good purchases that will help the team (specifically defensively) with Owen, Martins and now Viduka all fit and vying for places, they will certainly find the net.
