To my recollection, Suarez did pretty well as a physical player in the Prem, minus a biting incident or two, and are you really suggesting that Neymar and Messi, each their own supercharged mighty-morphin Hazard, wouldn't fare well in an English side?
Not to mention Mascherano, Rakitic, and Alves, who are all plenty physical for their positions.
I think you're delusional if you suggest that such a deep, talented side couldn't compete in the premier league because they're slightly undersized or lack the intense physicality that the premier league demands. They very much could.
