Watch: Incensed Conte snaps on Mourinho, yells in his face

Chelsea manager Antonio Conte and former boss Jose Mourinho had a heated exchange on the touchline at Stamford Bridge as the latter's Manchester United took on the Blues in this FA Cup tilt Monday.

The two tacticians exchanged verbal jabs, separated only by the fourth official, with Conte upset by a foul on Marcos Alonso by Antonio Valencia. He turned to Mourinho to express his displeasure, screaming at the Portuguese tactician.

It takes a brave man to step into the middle of a Conte-Mourinho screaming match, but referee Michael Oliver ran over to cool things down, probably by threat of expulsion.
