Internazionale defender Nemanja Vidic says he still needs time to adapt to Italian football.
The 32-year-old joined the Nerazzurri during the summer transfer window and was shown a straight red card for sarcastically applauding the referee on his debut with Internazionale.
"I still have to adapt to Italian football," Vidic said on Saturday.
"Playing here is difficult, I also have to adapt to referees in respect to physical contact."
Players in Italy are renowned for going to ground too easily and Vidic says he's learning to cope with the problem.
"I believe the referee's job is sometimes made tougher by the fact that some players want a foul or a penalty when there's no contact," added the defender.
"It doesn't happen that often in England.
"This is why I'm saying I have to adapt, not just the referees but also the behaviour of the opposition."
