NEWCASTLE Jets players have threatened to boycott the crucial Asian Champions League clash against Korean club Ulsan Hyundai next week if Football Federation Australia does not sign off on a payment structure for the prestigious tournament. Players aired their grievances during a lengthy meeting with representatives from the Professional Footballers Association in Newcastle yesterday at which a vote was passed not to travel to Korea unless their demands were met.As it stands the players are not guaranteed any remuneration other than regular wages."We are meant to fly out Saturday, but if it is not resolved we will not be on the plane. Simple as that," one player told The Herald yesterday, adding that they were making a stand on behalf of other A-League players who may be involved in the ACL.The PFA have been fighting for more than two years to introduce a standard player payment structure for the ACL."We tabled our original proposal for ACL payments in March, 2007," PFA chief executive Brendan Schwab told The Herald from Europe, where he is on business. "We tabled a specific proposal for this tournament in January 2009. We are now in May and FFA, as the bargaining agent of the clubs, is yet to table a proposal."The players are very frustrated over the negotiations. They raised with us their concerns and the possibility of boycotting the match against Korea."If the players were to strike, it would cause enormous embarrassment for the FFA and the A-League, but Schwab said direct action would be "the absolute last resort". An FFA spokesman confirmed yesterday that clubs were under no obligation to pay ACL bonuses. Negotiations between the FFA and the PFA over general ACL payments and conditions have begun, but no resolution has been reached.As a result the players are unlikely to have a legal platform to strike.Jets owner Con Constantine said the issue was between the PFA and the FFA, but any player who did not want to represent Newcastle was free to leave."I will send the [remaining] young boys and tell them to do their best," Constantine said."But anyone who does not go will have to find another club. I do not want them here."Constantine, who came under fire for not delivering a promised bonus after the Jets won the 2007-08 A-League title, said he would abide by whatever payment structure FFA agreed to."This has nothing to do with the club, it is a matter between the FFA and the PFA," he said."Why drag us into it?"We will not be blackmailed by the PFA or players."No one not the players or the PFA is above the club."Constantine will meet with the players on Thursday where they will be "told a few home truths".A draw against Ulsan would be enough to take the Jets through to the knockout stage and a guaranteed $US50,000 ($67,142) in prizemoney. The club has already earned $US100,000 to date in the group stage and would add either another $US40,000 for a win or $US20,000 for a draw against Ulsan.Constantine said the club had not yet received any of the prizemoney. "The only money is the money going out of my pocket," he said. The players became upset last week when they learned that Chinese club Beijing Guoan was paying each player a win bonus of $4000. It is understood the PFA are seeking a standard $1250 per game per player and a percentage of prizemoney."The proposal for the Australian players is about 20 per cent of what we know most Asian clubs are paying their players," Schwab said."We have taken into account all the relevant economic circumstances and conducted ourselves very fairly."Jets players have also called for protocol to be introduced regarding travel arrangements after they endured a horror return trip from Nagoya last month.Schwab was hopeful of a quick resolution."Really, it is straight-forward negotiation," he said.Jets coach Gary van Egmond was annoyed by the timing of the issue but was confident it would be dealt with quickly."With a game as important as this, the last think we want are disruptions," he said. "For me it is pretty harsh to criticise the club when we are clearly the meat in the sandwich."I'm sure between the FFA and PFA they will come up with a suitable arrangement that is fair for all players."
