AMIR KHAN has been hit by a walkout by coach Alex Ariza. (Boxing)

Former light welterweight champ Khan has been in Manilla preparing his bid to
recapture the WBA and IBF titles from Lamont Peterson in Las Vegas on May 19.

He has been training with stablemate Manny Pacquiao, who faces Tim Bradley in
a world title defence in Vegas in June.

It is claimed Ariza walked out four weeks before Khan’s rematch to go and
assist Julio Cesar Chavez prepare for a bout with Andy Lee.

Khan’s trainer Freddie Roach said: “What Alex has done is very
unprofessional.He’s not a pro. There are thousands of good conditioning
coaches but few good boxing trainers.”
