What's impressive about those clips of Pereira is that he's beating players through skill/nouse and not pace/power. I know I've rambled on about it a few times before but technique/touch/vison etc. is far more important at the top level than pace and power. Pereira seems to have those qualities so I'm looking forward to seeing him in action.
That Ireland side beat Portugal in Portugal recently so it shows you how talented that Belgian team are, or how the how bad the Portuguese team were.
