premise: Blackburn's South African striker Benni McCarthy has admitted he has found life in the Premiership tougher than he had expected.
  McCarthy, who joined Blackburn in a 2.5-million-pound summer transfer from FC Porto, admitted he was finding English football physically challenging, although his nine goals in a struggling side suggest he has not had that many problems adapting.
  "It's so physically demanding and every game is like a cup final," he said. "I've played in Holland, I've played in Spain, I've played in Portugal, and not every game is so fast and so difficult.
  "Even if you're playing against the bottom team in the league, it's as difficult as playing Manchester United, Arsenal or Chelsea. In Holland, Spain and Portugal only a few teams made you really work hard and concentrate for 90 minutes. Here you have to be in top form in every game."
   Why has McCarthy found life in the Premiership tougher than he expected?
hypothesis: be in top form in every game
