CHELSEA boss Andre Villas-Boas is unrepentant over his criticism of referee Chris Foy in Sunday’s defeat at QPR, despite being asked to explain his remarks to the Football Association. Villas-Boas insists Foy, who sent off Didier Drogba and Jose Bosingwa and booked seven Chelsea players, was “card happy” and “extremely unfair”. “I don’t think I said anything I shouldn’t have,” he said. “I would never question the referee’s integrity. But the fact is that, at the moment, we are paying heavily in terms of major decisions.” Villas-Boas has until Friday to respond to the FA, as do the club over a charge of failing to control their players.
