Jamie Carragher and Gary Neville, Sky Sports colleagues in the studio, have traded banter online over the World Cup.
Neville is currently working out in Qatar covering the tournament as a studio guest for ITV and beIN Sports, whilst Carragher is following the World Cup from home.
The former Liverpool man tweeted out a screenshot of Neville's claim that 'Players aren't fearful of Lionel Messi anymore', after a poor run of international form from the 35-year-old Argentine star.
However, Messi turned in a good performance in his country's 2-0 win over Mexico on Saturday, and scored the opener with a blistering strike from 25 yards out.
