Mourinho queries ref's standards

London - Chelsea manager Jose Mourinho made a surprise appearance on a British soccer television show on Sunday, to query the standard of refereeing he has seen this season.

Mourinho, whose side drew 1-1 at home to Burnley on Saturday, was frustrated that referee Martin Atkinson sent off Nemanja Matic in the game for pushing Ashley Barnes after the Burnley striker's aggressive challenge on him.

The Chelsea boss was furious with Barnes' tackle insisting "the consequence for Matic could be end of career" if Barnes had made stronger contact with the Blues midfielder.
