Stan Collymore has slammed Manchester City star Robinho.

In his column for the Sunday Mercury, former Liverpool and Aston Villa star Collymore wrote: "This weekend, I witnessed quite possibly the single worst performance ever seen in the Premier League ... and that makes me fear for Mark Hughes.

"Playing for Brazil in midweek, Robinho was world class, unbelievable. But for Manchester City on Saturday, I swear he didn't move more than 10 yards all game.

"It was an utter disgrace, because City were playing with nine men.

"His Brazilian team-mate Elano wasn't much better, again after a world-class performance against Italy at the Emirates.

"I don't care what excuses they both make, you simply cannot go from the sublime to something so ridiculous without there being an underlying reason."
