Source: BBC SportLuis Suarez did not appreciate "the seriousness" of biting Branislav Ivanovic when he argued against a long ban, says a Football Association panel.
The Liverpool striker accepted a three-game violent conduct ban, but claimed the incident did not deserve more.
However when he was banned for 10 games he decided not to appeal.
The FA's written reasons for the ban stated it should send out a "strong message that such deplorable behaviours do not have a place in football".
The 21-page rationale, published by the three-man independent panel appointed to rule on the case, noted that Suarez's tussle with Chelsea defender Ivanovic in the teams' 2-2 draw at Anfield on Sunday, had been "seen by millions of viewers both domestic and overseas, as well as generating a great deal of interest and debate amongst countless number of people".
