Jose Mourinho used Chelsea striker Diego Costa to wind up opponents last season.

The now Manchester United boss was sacked last December in his second spell at Stamford Bridge.

The Daily Mail says the Special One deliberately fired up star man Costa to provoke opponents in the latter stages of his tenure.

Costa, 28, is well-known for his fiery personality on the pitch and picked up 16 yellow cards in his first two seasons in west London.

However, the Spain international seems a different player under Antonio Conte this year – despite clashing in the dressing room earlier this season.
