We won't be kicked off top spot, Mourinho warns Blues' rivals
Pompey had been wound up to close the class-gap with a volatile approach and were lucky not to incur more than four bookings - especially abrasive midfielders Richard Hughes and Salif Diao.
Mourinho took off Joe Cole before the end after Portsmouth players accused him of diving for the penalty that clinched victory midway through the second half and what should have been another soon afterwards when referee Phil Dowd gave a free-kick inches outside the area.
