Liverpool legend Jamie Carragher has transformed himself into a footballing expert since hanging up his boots in 2013.The Reds came close to winning their first Premier League title in the season following his retirement but fell apart in the final few games.Under Jurgen Klopp, the attack-minded Liverpool look like they could genuinely challenge the top clubs at the top of the table this season.Manchester United and Manchester City are the two clear favourites but - with Sadio Mane, Mohamed Salah, Roberto Firmino and Philippe Coutinho leading the line - experts are beginning to take Liverpool seriously as title contenders.The 39-year-old Sky Sports pundit spends plenty of time on social media and is regularly ruffling feathers and seeing his tweets go viral.Carragher's Liverpool career spanned 17 years and made 737 appearances for the club, including 150 European appearances.The born and bred Scouser won eleven trophies in total and also racked up 38 international caps for England.Carragher retired in 2013 and still has strong ties with the club but it appears he does not retain a good relationship with one former teammate.Plagued by injures, 31-year-old Jose Enrique officially retired today and Carragher was hoping to send him a 'good luck' message on Twitter.However, the playful pundit instead tweeted a screenshot showing that Enrique had decided to block him on social media.

History of their 'beef'

In 2013 Carragher said, "I stopped talking to Enrique in the end, I had no idea what he was going to do and he didn't listen to me anyway."

In 2015, the Sky Sports regular had more to say about the Spaniard who spent five years at Anfield, eventually leaving in 2016 when his contract expired.

“[Enrique] said he wanted to fight for his place," Carragher wrote in his Daily Mail column. "He added that he had looked to Spain for a move but economic conditions make it difficult.

“That translates as: I’m staying because no-one in Spain can afford me and I don’t care if I don’t play (just like last season) because I’m waiting to go on a free next summer when my contract expires.

“I am sure there are clubs in England or Spain who would want him for less money. It is about whether he really has the hunger to play even if it means a pay cut.”
