Liverpool star Raheem Sterling appeared to take a swipe at former footballer-turned-pundit Robbie Savage on Twitter at the weekend.
The ex-Leicester City and Derby County player commented on the fitness of Andy Murray and Novak Djokovic while watching the pair battle it out in the Australian Open final.
He tweeted: "When you watch these 2 play tennis it amazes me how modern day footballers complain of tiredness embarresing really !"
In response, Sterling retweeted the comment and then posted: "back to bed for me!!!"
The 20-year-old received criticism earlier this season when he was rested for an England game after he telling manager Roy Hodgson that he was too tired to play.
