Just using those names there:
Wijnaldum - Always seen as a top talent but didn't have the attitude to suceed at the top level. Also an injury concern before his move thanks to a back injury. Always linked with top teams but never made the move. No wonder he went down.
Shaqiri - Similar story, massive ego and bad attitude yet never succeeded.
Affellay - Big injuries cost him at Barcelona, Stoke took a punt on him and it may pay off.
Sissoko - Disappointing one because we were linked initially and I think it was a decent price - 8/9 million maybe when we were crying out for a midfielder like that. Massive ego and actually not that good.
Bojan - Similar to Affellay, injuries plus the hype about being the next best thing at Barca made he didn't succeed. That's why he bounced around Roma, Milan and Ajax.
Stoke and Newcastle will take punts on those players, we haven't been able to in the past. We'll get talent, just not overhyped talent with baggage.
