Chelsea boss Guus Hiddink has refused to be drawn in on a debate over whether Diego Costa bit an opponent in Chelsea's defeat to Everton on Saturday evening.
The Spain international was shown a second yellow for a coming-together with Gareth Barry late on at Goodison Park, with replays appearing to show the striker biting the Toffees midfielder.
Roberto Martinez revealed after the game that, following a conversation with Barry, he did not feel as though the matter was worth pursuing.
These views are echoed by Hiddink, who took the opportunity when asked whether Costa can benefit from some "anger management" classes to joke that his star forward could perhaps watch the film carrying the same title.
"There are movies about that, I think," he is quoted as saying by The Telegraph. "One movie with Jack Nicholson. Maybe we (him and Costa) go and watch it together."
Costa has scored or assisted 17 goals in his last 16 outings, but could not make a telling difference in the 2-0 defeat to Everton.
