The 23-year-old returned to Old Trafford last summer for a world record fee of £89m after spending four years at Juventus.
He has made a mixed start to life under Jose Mourinho, producing the occasional moment of brilliance but ultimately proving unable to impose himself on regular basis.
Speaking on Sky Sports, Rooney was quick to defend the Frenchman.
“Paul is a fantastic player,” he said.
“I think he’s working hard and he’s doing well. As always, it takes time to settle. I think he is a fantastic player and he will shine for us this season, there is no doubt.”
If you wade past the swathes of slander aimed at Pogba in recent weeks and the furious agenda quickly forming against him, it is easy to tell that, contrary to what the social media football experts proclaim, this is someone with an exceptional amount of talent.
Even during a time of adjustment, with Pogba still feeling his way into life at Old Trafford and Mourinho still searching for his best starting XI, the 23-year-old’s raw ability on the ball – namely his control, awareness, range of pass and general presence above anything else – has shone through.
Perhaps some expected an immediate and constant supply of rip-roaring, game-changing moments from the Frenchman, and have been left feeling short-changed. Pogba’s natural ability, however, is unquestionable, and the midfielder will only continue to improve over the coming months.
