The former Red Devils left-back expects to see vast improvements in Jose Mourinho’s side – due to some exciting summer signings – following their sixth place finish last season.
Irwin has also tipped Marcus Rashford to kick-on in front of goal following United’s “over-reliance” on Zlatan Ibrahimovic last season.
“I expect Paul Pogba to be a really powerful player this year,” said Irwin, speaking on behalf of Marathonbet.
“I expect Manchester United to challenge for the title. More consistency is needed. We drew too many [last season] and I think more goals are needed from different areas.
“Last season there was an over-reliance on Zlatan. Rashford, I think, will score more goals.”
Irwin made 529 appearances for the Old Trafford side, and thinks it has been a summer of good business in a transfer window of “eye-opening” amounts spent on players.
Defender Victor Lindelof, striker Romelu Lukaku and midfielder Nemanja Matic have all been snapped up by Mourinho.
“Lindelof will take a bit of time but will turn into a very good player,” Irwin said. “Lukaku and Matic are good additions. Matic is a really experienced, solid performer.”
But Irwin feels United will have a fight on their hands, as others battle it out at the top of the league, despite tipping both Chelsea and Tottenham to find this campaign harder than the last.
“Chelsea have got European football and Spurs are now at Wembley,” said Irwin.
“Manchester City will be strong this year and Arsenal have bought a striker which was needed. I wouldn’t dismiss Everton. It’s going to be a very competitive league I think.”
