Welcome to SportsNation! On Friday, we're going inside the boxing ring when legendary trainer Freddie Roach stops by to chat about his pupil Manny Pacquiao's fourth fight against Juan Manuel Marquez, which is set for December.

Marquez (54-6-1, 39 KO) takes on Pacquiao (54-4-2, 38 KO) for the second time in a year on Dec. 8. MGM Grand Garden Arena in Las Vegas will host the bout, which will air live on HBO PPV.

Roach, a Massachusetts native, won the trainer of the year award in 2003, 2006, 2008 and 2009. As a professional boxer, Roach went 39-15 before retiring in 1986.
