Chelsea midfielder Juan Mata insists manager Andre Villas-Boas is doing "very well" despite the club struggling to keep pace in the title race.
The Blues are in a real battle just to qualify for the Champions League this season and Spaniard Mata, signed from Valencia in the summer, admits that the two Manchester clubs are in pole position for the title.
Mata told Marca: "It's true we've had a little crisis of results, but Villas-Boas is doing things very well and both the players and the club have a lot of confidence in him. He won everything with Porto last year."
