That's the verdict of Old Trafford legend Ryan Giggs, who's suggested Jose Mourinho, Paul Pogba and Zlatan Ibrahimovic hold the key to the Red Devils' chances of glory this season.
United are looking to build on the Europa League and EFL Cup success they enjoyed under Mourinho last season as they go in search of their first title since 2013.
They're currently eight points adrift of Premier League leaders City though and that could be increased if they fail to beat Newcastle United this Saturday (5.30pm).

Giggs, who won 13 titles with United, still thinks his old side have what it takes to contend with City though.

"Tottenham have also been impressive and I had thought they would struggle going for the title with the Wembley and playing in the Champions League but they've gotten over it really well, so I'd have them third in the mix," he added.
United and City are set to renew their rivalry at Old Trafford on Sunday December 10.
Mourinho's men have fixtures against Newcastle, Basel, Brighton, Watford, Arsenal and CSKA Moscow before that clash.
