John Aldridge has accused Luis Saurez acting like a 'rat' during Barcelona's 3-0 victory over his former side Liverpool last week.
Suarez opened the scoring in Champions League semi-final first leg match against his former side before Lionel Messi scored a brace to put Barcelona ahead with points.
But Suarez, who played for Liverpool between 2011-2014 was heavily criticized for celebrating against his former club.
John Aldridge even slammed him for his actions by saying: “Suarez behaved like a rat in the Champions League semi-final against Liverpool and it was out of order,” Aldridge told the Irish Independent.
He added: "What was not acceptable was his antics on and off the ball, as he got into the faces of Liverpool players, fell over any time anyone went near him and tried to get his opponents booked at every opportunity.
"He was sneaky, he was nasty and he was everything people used to tell us Suarez was when everyone at Liverpool was trying to defend him.
"We know this is a guy who would run over his granny to score a goal, but everyone should have some respect for those who have been good to you in the past, but Suarez threw the support Liverpool gave him back in our faces.”
And Aldridge believes Suarez should have shown his class when coming up against his former side who backed him to the limit.
"It would have been easy for Liverpool to turn their back on Suarez after his infamous clash with Patrice Evra or when he sank his teeth into Branislav Ivanovic, but our club stands by their own when times are tough and that's what all did with this little striker."
