PROFESSIONAL FOOTBALLER'S ASSOCIATION (PFA) chief executive Gordon Taylor has confirmed the union have been contacted by Sunderland players about their manager Paolo di Canio and that it is investigating the recent fines issued by the Italian.
Di Canio has been speaking publicly about what he sees as a lack of discipline among the players at the Wearside club, seven of whom he fined last week.
Defenders Phil Bardsley and Matt Kilgallon were dropped from the matchday squad for Sunday's Premier League clash at Tottenham after they were pictured celebrating on a night out in a casino earlier in the week, with the former lying on the floor covered in £50 notes.
Di Canio, in an angry rant, stressed the need for the matter to be addressed and also claimed the PFA "excuse people that behave like Phil Bardsley ... (even though) the PFA don't pay them, it's a private club that pays them."
Taylor said members of the Sunderland squad had been in touch with the PFA regarding Di Canio and the union was investigating.
"We know Paolo ... is a bit volatile," said Taylor. "But he knows, from when he was a player with the PFA, what we are about.
"One point he made was about Sunderland being able to do what they want – well they can't.
"We obviously agree with discipline, but that has to be in line with the Football Association and the Premier League. There is a due process.
"It is not going to help matters blasting players in public, but that is what he has done, so we will deal with it."
