Football will continue to explore a clearer path out of the coronavirus crisis on Wednesday as players' unions meet to discuss wage deferrals and contract extensions.

Professional Footballers' Association chief executive Gordon Taylor has warned any clubs imposing deferrals must be blocked from making signings until the resulting debts are settled.

And FIFPRO general secretary Jonas Baer-Hoffmann says while legal issues remain to be overcome, the "spirit" of existing contracts mean they ought to remain valid until the extended end of the current campaign.

Taylor does not believe a uniform rule can be established for wage deferrals but is keen that clubs be prevented from claiming hardship them moving into the transfer market.

He told the PA news agency: "It's not a time to be relaxing regulations on financial propriety when we have already had problems with Football League clubs such as Bury.

"If a club is doing deferrals then the regulations state that they would be embargoed from signing any players."

FIFPRO officials have been part of working groups established by FIFA and UEFA to look into the consequences for players whose contracts generally run out on June 30.

"You could very much argue that the spirit of the contract is that it runs until the season is over and a new contract starts with a new season," said Hoffman.

"Nevertheless, there are legal obstacles with mandating such an extension which we're trying to manage as well as we can, but we are very concerned that we might end up in a situation where (clubs) pick and choose who is being retained for the last couple of months of the season and who is not."
