Podolski, Marko Marin, Adrian Mariappa and Gylfi Sigurdsson for me.
Podolski didn't perform well at Bayern, although I have to concede he is very impressive for Germany. Marin isn't anything special, just seems to be a squad player Chelsea picked up at a reasonable price; it's a good deal, but don't expect him to set the Premier League alight! He'll probably just play a few games, perform to a decent standard, and then leave, a la Deco.
Mariappa isn't anywhere near Prem standard, more suited to the Championship; or even League 1! And Gylfi is too selfish for my liking, yes he's a good player, but he won't really fit in at Spurs either! Even if Modric leaves (which is getting likelier by the day), I still don't think he'll fit in with the likes of Bale, Lennon and Adebayor. However, that's just my opinion, and I'd like to see him prove me wrong!
There's not been that many big name transfers yet this summer, but as clubs make more signings, there'll be a lot more potential flops to pick out!
Where did you get that from? Deary me
