Manchester United defender Patrice Evra believes Chelsea will be their biggest title rivals this season and not Manchester City.
The blue half of Manchester has once again been busy in the transfer market this summer, spending in excess of £50million on Gael Clichy, Stefan Savic and Sergio Aguero.
Chelsea, meanwhile, under new boss Andres Villa-Boas, have been less active during the close season.
Only youngsters Thibaut Courtois and Oriol Romeu have arrived so far, though Anderlecht striker Romelu Lukaku is believed to be close to sealing a £18million move to Stamford Bridge.
However, Evra believes Chelsea's greater experience in the title race means they will be the biggest threat to United's dream of a 20th league title and not their big-spending city rivals.
"Chelsea are our main adversary. I don't rank City," the 30-year-old told France Football.
"They [City] have bought a lot of players and will be under big pressure. Chelsea has experience and so remains our most dangerous adversary."
Evra also praised some of United's young players who have stepped up to the first-team following the retirements of established stars Paul Scholes, Edwin van Der Sar and Gary Neville.
"Those young players, like Tom Cleverley, will surprise a lot of people," added the Frenchman.
"They are hungry, bringing in a fighting spirit and they are listening."
