Wenger said: "Yes, foreign players brought this into the English game. But I must say the English players learn quickly.
"The foreign players have brought good and bad things. In England you respected two things - that you got well kicked but, on the other side, that they did not go down for nothing.
"Another thing I admired here in England is that you never surrounded the referees to give a yellow card to somebody else, you let the referee make a decision. But that has gone as well. Not everywhere, but there is a trend now to surround the referee and give a yellow card - and that never happened when I arrived."
