Nani has admitted a lack of concentration was to blame for pitching Manchester United into the most important derby clash of Sir Alex Ferguson's career at the Etihad Stadium next Monday.
Following United's 4-4 draw at home to Everton and Manchester City's 2-0 success at Wolves, Ferguson and his players know that, not only will they surrender top spot if they lose, there will be nothing they can do to alter the situation should City win their final two games.
"There is anger from the players," said Nani. "The concentration was not the best in the last few minutes - that's why they were able to create chances and score goals."
