Ex-Liverpool chief executive Ian Ayre has spoken of the difficulty surrounding the sale of Luis Suarez to Barcelona in 2014, as reported by the Liverpool Echo.
Ayre, who stepped down in February, was giving a speech to students of John Moores University and claimed that it was tough letting the Uruguayan leave for La Liga side Barca.
Suarez spent three-and-a-half seasons as an Anfield player and was hailed as one of the greatest to ever wear the shirt before leaving for a whopping £65m.
The man who sanctioned the deal Ayre lifted the lid on why it wasn't so straightforward and pointed to his infamous actions at the 2014 World Cup involving Giorgio Chiellini.
The new managing director of German club 1860 Munich said: "The hardest one out [transfer] has to be Suarez, because of a, nobody wanted him to leave and b, halfway through the process he bit somebody at the World Cup.
"I remember the sporting director of Barcelona calling me during that game, immediately as Suarez bit the player, and he said to me 'My friend, he's bitten somebody, how can this be the price?' I said: 'He'd already bitten somebody when you first bid!'"
Suarez was widely condemned over the incident and received a fourth-month ban from all football-related activity for his actions - a ban that meant his debut for new club Barcelona got delayed.
The 30-year-old has enjoyed a fruitful few years in Spain since his move, scoring 116 goals in just 143 appearances and forging one of the most feared three-pronged attacks in world football alongside Lionel Messi and Neymar.
