The Gunners manager has previously complained about the robust nature of some clubs in the Premier League but did not take a backwards step when asked to comment on West Ham United striker Andy Carroll's collision with Manchester United goalkeeper David de Gea in the 2-2 draw on Wednesday night.
"I don't have a problem with players who go in completely 100 per cent, because that is what you want to keep in the English game," he told the Daily Mirror. "It is a strength.
"Sometimes I watch foreign games and after 20 minutes you are bored because every time somebody goes down it is a foul, and you say: 'Come on!' That is not football, as well. We do not want to lose the strengths and what makes English football attractive but the intention of the players has to be fair.
"The physicality of the English game is one of the attractions of it. I don't think it holds players back. In fact, the opposite, the foreign players who come to England improve and you get that aspect of the game as well.
"When I brought [Robert] Pires here he was not especially physical player but no-one could stop him from playing his game. [Marc] Overmars, [Dennis] Bergkamp - nobody could stop them.
"You cannot say it's physical or it's kicking, it's just that the commitment is high - and that's what you want."
