West Ham United defender James Collins has branded Manchester United winger Adnan Januzaj's diving antics as "cheating".
Januzaj was booked for simulation in the first half of United's 3-1 win over the Hammers on Saturday, after Collins pulled out of a challenge between the two.
United boss David Moyes has spoken with Januzaj after being cautioned for a diving for the second time this season and Collins has reacted angrily to the wideman's behaviour.
"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."
Amid the booking, Januzaj went on to score his first Old Trafford goal after leaving Collins on his knees as United secured their fourth successive win.
Moyes has already been forced to defend Ashley Young this season after a series of dives and the United boss admits he has discussed the issue with Januzaj.
"If you look at the last two games and the amount of tackles that this boy has had to take, he has had more than any other player," Moyes said.
"He thought he was going to get scythed down. He's been getting kicked in every game. We'll talk to him about it but I said last week that there were a lot of people having a kick at Adnan because he's very difficult to mark and he's elusive the way he moves.
"It can bring defenders into tackles but it's the referees that have to call it right. I just hope that they don't wait until he gets a bad one before they get it right."
