Rooney’s former club are also enjoying a resurgence, with a 4-2 win over Brighton making it three on the trot and lifting them up to sixth place – level on points with Manchester City and one clear of Liverpool.
Part of that success has been down to the form of forward Bryan Mbeumo, who has scored three of his five goals in the last two games.
Rooney admitted he was not convinced when United brought him to the club in the summer for £65m from Brentford, but said the 26-year-old Cameroon international is now living up to expectations.
“His energy, his work-rate, his desire, is what you need to be a United player. I did say that I was a little bit unsure, but I think what he’s shown is he belongs there,” added Rooney.
“He’s been consistent with his performances, I think that’s the main thing. If you’re consistently getting into the right positions, and getting chances, you will score 20 goals a season.”
