Super Eagles captain has opened up on the reason Nigeria failed to qualify beyond the round of 16 at the 2014 World Cup in Brazil. The former Chelsea star revealed there was a dispute between the Football Federation and the players which led to a boycott in training. The men in Green and White lost to France by 2-0 by two second half goals as the three-time African champions failed to go beyond the last 16 for the third time asking. mikel_john_obi Unfortunately due to circumstances beyond my control I will not be on the field for our game v Serbia tomorrow. I am sad, and frustrated, but giving my full support to the team for another win “There were a lot of problems in the camp which a lot of people didn’t see, the media didn’t see we kind of hid it under the table,” Mikel told the Guardian. “The relationships between the players were not good and there was no discipline. There was no good feeling, no good vibe. “It almost got to people being pinned up against dressing-room walls, although not quite. It was confrontation and arguments. Players wanted to do their own thing and they didn’t think about the team.” The 33-year-old playmaker is also happy with the massive transformation Gernot Rohr has brought to the team in recent years. He stressed that the present group is the most disciplined since he joined the team in 2005 and he believes the attitude in camp will bring positive results. “The coach and myself, as captain, have tried to make these young players realise that we are a team, not individuals,” Mikel continued. “If you don’t want to play together, you are welcome to leave. It’s amazing now to go to camp. You can feel the good feelings. “I have been in the national team since 2005 and I haven’t seen this discipline before. It is meetings, being on time, the training. "Sometimes a player has the hump because he knows he is not going to make the team and, before in the national team, he just strolls around. "Now, you have to train properly. If you don’t, you are leaving the camp. The coach has changed the whole mentality.”
