The former PSV Eindhoven man was bitten by the Uruguayan in a match against Ajax in November 2010, which resulted in a seven-match ban and heavy fine for Suarez.
Having received an apology from the striker at the time, Bakkal is amazed that Suarez has repeated the incident.
"I saw it and it was unbelievable. It's something you can never imagine happening on a pitch," Bakkal told The Sun. "It happened once already. At first I thought maybe it was an accident but, apparently, he loses it sometimes. I don't know what to say.
"I thought he meant it when he said sorry. I think he wants to win so badly that he loses his mind sometimes but afterwards he comes to his senses. I am a footballer as well and this affects all of us, but for me it's more important to leave all this behind me.
"It doesn't belong on the pitch. It was the end of him in Holland. Now we just have to wait and see what the FA does - and then what his future will be in England."
The FA have since charged Suarez with violent conduct.
