Tottenham defender Lee Young-Pyo has accused Cristiano Ronaldo of diving to win a penalty.
Ronaldo controversially won a penalty for Manchester United in their 4-0 win at White Hart Lane last weekend.
The Portuguese international went down in the box under a challenge from Steed Malbranque with replays showing there was minimal contact between the pair.
Lee was unhappy with Ronaldo's antics and believes the flying winger dived to win the penalty.
"Steed and I didn't touch him. I think he dived," said Lee.
"I don't know why he fell. It's a great pity.
"I can't understand why some players would do that. I'm disappointed."
Meanwhile, Spurs boss Martin Jol has called on his players to toughen up after a disappointing run of form.
Spurs currently sit in 11th spot in the table and have taken just two points from the last 15 available.
Jol wants his side to show a bit more bite, especially in midfield in a bid to get out of their slump.
"When we beat Chelsea in November, we had a bit more grit and that is what you need to beat a top team," said Jol.
"You need everything - not only on the ball, but off the ball as well.
"You have to stay with the runners, turn with the man and don't let them run into the box.
"But we tend to do that sort of thing all the time and we have to learn.
"Huddlestone is a great example. He is great on the ball but he has to win his battles too and the same goes for Zokora.
"We didn't defend well against United and in midfield, we didn't win enough balls."
