He went a-chomping whenever he wanted a move. Did it once at Ajax, twice here. Other players down tools to force a move. Suarez ate people.
You could say he downed tools for the Arsenal move (in a summer in which he also pushed for a move to Real Madrid).
There's other parts to that as well:
1) His attitude to it. Even without the other two bites, minutes after the Uruguay-Italy WC game, he (or his pr team) put out a statement saying that he didn't bite him; that he lost his balance and his teeth casually fell on Chiellini's shoulder.
2) the attitude of our fanbase to the previous point and other times: as soon as said statement came out, we had people here agreeing with it. Also, people denying he dived. I like to think we're a bit less blinded by tribalism in the PL all in all, and imo he brought the worst of it.
3) I know many players kinda fake the love for the club they are playing for, but I always felt it more with Suarez. Case in point, the summer he pushed for a move to Real Madrid, he said that was because the
English press were hounding him. Not too bad as a mitigating factor for us, but then three weeks later he put in a transfer request for
Arsenal.
