And he compared the situation to Luis Suarez at Liverpool, when the Uruguayan received a lengthy ban for biting Branislav Ivanovic.
Suarez later committed the same offence at the World Cup against Georgio Chiellini, away from Liverpool, and received a further ban.
I'm a fan of Costa tbf.... But he deffo thought about a bite there...— Robbie Fowler (@Robbie9Fowler) March 12, 2016
