Chelsea manager Andre Villas-Boas believes that Alex Ferguson and himself should take a back seat during their sides' Premier League clash at Old Trafford on Sunday.

The two clubs go head to head this weekend, with the Red Devils edging the Blues by two points in the table.

"Our importance in the game is minimal," Villas-Boas told Sky Sports News "It is for the players to feel motivated, enjoy the game and exploit their talent.

"It is for us managers to try to promote that talent, incentivise their motivation and lead them to success. In my opinion, our percentage [of contribution to the game] is always small."

Meanwhile, United boss Ferguson believes that Chelsea are genuine title contenders this season ahead of their showdown on Sunday.
