Doesn't that regrettably go with the territory these days? Commit a bad foul and then pretend you're injured in the hope to avoid the referee's retribution.
On a separate issue, the referees have been quite lenient in this tournament with cards especially for tug backs where it used to be an automatic yellow. I think that has been an improvement. However, where the game is getting out of hand is the automatic feigning of injury for 90% of tackles. The having to leave the pitch following treatment was an attempt to reduce this but now players are rolling around and then telling the trainer not to come on. How to deal with this? It is gone beyond a joke.
