Nigeria coach Stephen Keshi wants his players to show more commitment and professionalism or stay away from the squad.
Super Eagles players received a dressing down from Keshi after slacking off in the second half of their 2-2 draw with Liberia in a 2013 Africa Cup of Nations qualifier.
“Sometimes I feel the right mental attitude and hunger is lacking in our game and I won’t condone that,” Keshi told BBC Sport.
“The body language must change and must correlate with our game plans.
“We have a very simple approach and we expect everyone to understand and respect that at this level.”
