The Frenchman was named captain for the second game running in the absence of Antonio Valencia, but failed to impress despite scoring a late consolation from the penalty spot.
'There's a lack of leaders in the team,' Scholes told Optus Sport. 'We thought Paul Pogba might be the ideal candidate to be that leader but he wasn't there today. He had another really poor game. He's so inconsistent.
'Pogba's playing the ball out of play, he's overhitting passes, he's hitting passes short, he's getting caught in possession.'
Raiola, however, took umbrage with the comments and posted an impassioned riposte on Twitter on Tuesday morning, claiming he would have 'sleepless nights' if United sold their club-record signing.
