Andy Murray body language remains a major weakness, warns Mats Wilander

Seven-time major champion Mats Wilander is backing Andy Murray to win two or three more grand slams but says the Scot’s body language is still a key weakness against the top players.

Murray is likely to be the calmest man on court when he begins his US Open campaign against volatile Australian Nick Kyrgios today but the Scot remains his own harshest critic when struggling in the heat of a battle.

After their most recent meeting in the French Open third round, which saw Kyrgios defeated in straight sets, Murray took to social media to apologise for his colourful language, which had caused some viewers to complain after being picked up by television microphones.
