Brandon Thomas-Asante scored twice at Fratton Park as Coventry City beat Portsmouth to extend their lead at the top of the Championship to four points.
The Sky Blues stormed ahead in the first half thanks to a nicely worked corner routine that ended with Brandon Thomas-Asante firing the ball into the net from close range.
Managers Frank Lampard and John Mousinho had to be separated just before the goal, involved in a fiery exchange after the home side had appeals for a penalty waved away.
Coventry then doubled their lead in the second half as Pompey were chasing an equaliser, Thomas-Asante ran clean through on goal before producing a fine finish to make it two.
Pompey fought back late on as Makenzie Kirk lobbed Carl Rushworth in injury time but the Sky Blues were able to hold off late pressure to pick up all three points.
For now Coventry have a bit of breathing room at the top of the table but second placed Middlesbrough have the chance to reduce that to just a one point lead if they beat Sheffield Wednesday on Wednesday.
