Inter Milan midfielder Fredy Guarin has declared Jose Mourinho as the best coach in the world.
The Colombia international has been linked with a switch to Chelsea in the January transfer window, and Guarin has said that the Blues boss is the finest around.
"Jose Mourinho? He is simply number one," Guarin told reporters.
"Under Walter Mazzarri [at Inter] we have started a new journey. With patience and hard work, I'm sure we can achieve great results.
"Qualifying for the World Cup with Brazil was a dream come true. Now we have to prepare as well as possible for the tournament proper."
Guarin has also been a reported target for Manchester United.
