Paul Pogba's lack of consistency is a source of 'frustration' for Manchester United fans.
That's according to former United midfielder Alan Smith, who was recently asked about Pogba. The Frenchman has been sidelined with a thigh injury since November, but he's close to making his return and he's been pictured in full training at Carrington.
But Pogba could leave United this summer on a free transfer, as there are just months remaining on his current deal at the club.
