England coach Sven-Goran Eriksson will step up his efforts to get Fifa to delay the deadline for World Cup squad selection at talks in Dusseldorf.
Eriksson will raise the matter at a meeting of World Cup coaches taking place on Monday and Tuesday.
The present 15 May deadline falls before England's final warm-up games.
And Football Association executive director David Davies said: "We have some confidence there is considerable support among the nations taking part."
Fifa president Sepp Blatter has hinted the deadline could be extended and he told a news conference in Lucerne, Switzerland: "This deadline has been fixed but it's a question for the organising committee of the Fifa World Cup and this will be on the agenda for their meeting of 15 March and we will discuss it then."
Germany's Jurgen Klinsmann supports Eriksson's proposal and the Swede claims he also has the backing of Holland boss Marco van Basten in a request to push the date back closer to the opening of the World Cup on 9 June.
The current deadline is more than three weeks before England's opener against Paraguay but also falls before the Champions League final.
Eriksson senses players' urgency
England's last two warm-up matches before Eriksson names his 23-man party are against Hungary and Jamaica.
Eriksson said ahead of England's friendly with Uruguay: "The date is too early and I know a lot of other coaches are not happy with it.
"We will bring it up at the coaches workshop and I'm confident it will be changed."
