West Ham United defender James Collins has branded the supposed diving actions of Manchester United youngster Adnan Januzaj "cheating".
Januzaj was booked in United's 3-1 win over the Hammers on Saturday, having gone down without being touched by Collins.
"It's cheating basically," Collins told Sky Sports News.
"I don't like to see it in the game. He probably thinks I am going to stick my leg out and he's probably already thinking about going over. Obviously he's taken a dive. He's a young lad, a great player, I'm sure he will learn. David Moyes seems to have this conversation quite a lot at his club with Ashley Young.
"It happens in football. He (Januzaj) is a great player and played very well at the weekend. He's learning the game and if he carries on playing the way he is, he is going to be a top-drawer player."
West Ham find themselves in 17th position in the Premier League table.
