Luis Suarez's remains "out of control", according to his previous bite victim Otman Bakkal who was stunned to see the Liverpool striker sink his teeth into Branislav Ivanovic's arm on Sunday.
The former PSV Eindhoven player, now at Dynamo Moscow, was bitten on the shoulder by the Uruguayan while he was at Ajax in November 2010.
It proved to be Suarez's final game for the Dutch side as he incurred a seven-match ban before signing for Liverpool less than two months after that violent outburst.
Following the incident on Sunday, Bakkal believes the Reds forward still hasn't dealt with his anger management issues.
"At the time Suarez said it was a one-off gesture, but now he has repeated it," the 28-year-old told reporters. "In those years he has not learned his lesson. Suarez needs to control his nerve and temper on the pitch.
"I have played against him and he talks too much."
Bakkal, a former Netherlands international, was left with a nasty wound on his collarbone after Suarez's bite. He says he has never encountered a footballer quite like the 26-year-old in his 10-year professional career.
"I know about the new case only by what I have read — I am surprised," he continued.
"I never provoked him (during the incident in Holland). He was very angry and the reaction was to bite me on the shoulder. He uses everything to try to distract defenders.
"I’ve never known anything like it as a professional."
