Nigeria coach Christian Chukwu is unhappy with captain Jay-Jay Okocha

Nigeria coach Christian Chukwu has slammed captain Jay-Jay Okocha and forward Yakubu Ayegbeni for their failure to travel to Rwanda for Sunday's World Cup qualifier.

The two England-based players did not turn up to the Super Eagles training camp in London earlier this week and both missed the flight out to Kigali on Wednesday.

Neither Nigeria captain Okocha nor Yakubu, who has scored two goals in the Super Eagles' Group Four campaign, have contacted Chukwu to explain their absence.

"Yakubu can go to hell, we don't need him," the Nigeria coach told BBC Sport.

"He doesn't have any reason for not being here - but we don't have much problem in attack because Obafemi Martins, Nwankwo Kanu and Stephen Makinwa can replace him."

"We are satisfied with those we have."

Chukwu's comments throw Yakubu's future international career with the Super Eagles into some doubt.

The pair have clashed before, when Yakubu was one of three Nigerian players sent home from the 2004 African Cup of Nations finals for indiscipline.

Nor is it the first time that Okocha has been conspicuous by his absence for a 2006 World Cup qualifier.

The midfielder missed the Super Eagles' trip to Angola in June last year, whereupon Nigeria suffered their only defeat of their Group Four qualifying campaign so far.

"As a captain, Okocha should be here leading his players," Chukwu explained.

"I still don't know why he's not here but I want to get to him and tell him that I�m totally disappointed."

"He's not given me any reason for his absence but I don't think there's any reason he can give that would excuse him not being here."

"Because he is not injured - he is fit - and he knows it's an important World Cup qualifier."

While Chuwku explained that Okocha's absence would hand a chance to younger players keen to impress for the Super Eagles, he did not rule out taking disciplinary action against his absent captain.

"Both the Nigeria Football Association and I want to talk to him," the coach said.

"If we don't get a satisfactory answer for his absence when we do, we might take action."

Nigeria lead Group Four with thirteen points, two clear of second-placed Angola, while Rwanda prop up the table with four points.
