Manchester City boss Roberto Mancini says Manchester United are favourites for the title this season.

Ahead of Sunday's Manchester showdown, Mancini insists United's summer spending means they should reclaim their crown.

The Italian said: "United are favourites for the title.

"They were a strong team anyway but they bought Robin van Persie and Shinji Kagawa.

"They added to their squad a player who can score another 25 goals."
