Former Liverpool defender Dietmar Hamann has criticised Ashley Young's "blatant cheating", insisting the Manchester United winger's antics are "worse than Luis Suarez has ever been".
Young has been widely condemned for going to ground under minimal contact and winning a penalty in United's Champions League draw with Real Sociedad on Tuesday.

United boss David Moyes shied away from accusing the 28-year-old, who was booked for simulation earlier in the season against Crystal palace, of diving, but Hamann believes Young is tarnishing his own reputation.
"Ashley Young is much worse than Suarez has ever been," Hamann told talkSPORT. "It's blatant cheating to try to win a penalty.
"You've got to be very careful because sometimes it's about protecting yourself in anticipation of a challenge. If someone comes to clatter you, your first instinct is to jump in order to protect yourself.
"(With Young) there was no protection (issue), it was a slight touch on his arm and he stated rolling over. I would say to Young, 'if you want to stay in the game for the next 10 years, you've got to cut that out'.
"I just think it's in him. It will be very hard for him to cut out. It's gone too far now."
There have been calls for Young to be punished through retrospective action, as was the case when Fulham's Sascha Reither was suspended for stamping on Adnan Januzaj, but PFA chief executive Gordon Taylor insists that is not an option.
"The feeling of all the stake holders is to be very wary of re-refereeing situations if the referee and assistants have 'seen' the incident in question," he said.
"If it is not seen it can be referred to the panel of ex referees. With that penalty decision the referee was very close and clearly saw Ashley Young being held, albeit briefly, and felt it was a penalty.
"There was a game at the weekend that featured two similar incidents. In one the player fell down, in the other the player tried to stay on his feet. As it turned out, neither were given penalties. It just highlights the fact nobody said refereeing was easy."
