Charlton boss Karl Robinson is set to discipline his players for their social media activity following the defeat to Portsmouth on Saturday.

The Addicks lost 1-0 in a below-par display on the club’s 25th anniversary back at the Valley.

Charlton players then hopped on a train to Newcastle for their Christmas party, something which was planned months in advance.

On their journey up north, Lewis Page and Leon Best uploaded footage and pictures on Instagram of team-mates laughing and singing just hours after suffering a second reverse in three league games.

It caused a stir among Charlton fans, with some claiming the players did not care about losing on such a commemorative day.

And while Robinson is happy with the camaraderie and team spirit shown by his players, sources inside the club have told News Shopper he is furious that pictures and videos were uploaded so soon after the defeat.

And as a result, the Liverpudlian is going to take disciplinary action against Charlton's stars.
