Arsenal came so close to Premier League glory for the first time since 2004 this season.
The Gunners had an 11-point lead over the Sky Blues at one point but a poor run in April saw that slip away.
Arsenal still finished the season in second spot, but five points behind Manchester City.
Now, attention has turned to who will try and knock Man City off their perch next term.
Liverpool’s form has improved a great deal in recent months, and they could be back at the top following some midfield investment, whilst Arsenal should be in and around the title picture again.
However, Roy Keane does not believe it will be either of those sides who will by taking Manchester City to the limit.
Asked who he sees as Man City’s biggest challenge next term, Keane told Sky Sports: “I’m going to go for Manchester United.
“I hope it comes from United. It will depend of course on the takeover and the recruitment this summer because they need a world-class striker.
“You would hope to think United can challenge next year but it’s going to be very, very difficult because Man City are brilliant and have a great, great manager.”
