Chelsea goalkeeper Thibaut Courtois has hit back at former Manchester United boss Louis van Gaal.

Van Gaal slammed Courtois and Chelsea's goalkeeper coaching after he was twice beaten by Lionel Messi in defeat to Champions League opponents Barcelona. Both of Messi's goals saw shots go through the Belgian's legs.

Courtois replied to Van Gaal through Sporza today: "When I hear so-called experts talking, I think they know nothing about goalkeeping.

"Van Gaal, for example, such people should not talk about goalkeepers. I know that I am doing well and I am growing to be in top form for the World Cup.

"I can laugh with those jokes on social media. After the game I sent to my friends myself: do you have a net for me? Those swear words are of course something else. There is a lot of jealousy, but I know that every day I work hard to get better."
