England's Football Association (FA) said it will work with Liverpool and Manchester City to help their fans attend next month's FA Cup semifinal at Wembley amid complaints about a lack of train services that weekend.
Liverpool supporters group Spirit of Shankly and City's We are 1894 said in a joint statement that the match would be difficult for fans to attend as engineering work scheduled for April 16-17 means there will be no direct trains to London from Manchester and Merseyside.

"More than 64,000 travelling supporters will be forced on to the roads, which will already be overburdened with bank holiday traffic," the supporters groups said.
In a joint letter to the FA on Tuesday, the mayors of Greater Manchester and Liverpool called for the semifinal to be moved from Wembley.
"This leaves tens of thousands of fans from all over our region in an unfair position, as supporters' groups from both clubs have made clear today," Mayors Andy Burnham and Steve Rotheram said in a joint letter to the FA Chair Debbie Hewitt.
"Without quick, direct trains, many people will be left with no option but to drive, fly, make overly complex rail journeys or book overnight accommodation.
"We believe the most obvious solution is to move this game to a more accessible stadium and offer to work constructively with you to make that happen."
The FA said in a statement released to British media that it would meet Liverpool and City to discuss match arrangements and announce further details in due course.
"We are also continuing to work with both Network Rail and National Express to find a solution so that supporters of both teams are able to travel to and from the fixture, with as minimal disruption as possible," the FA said.
The supporters groups called for the match to be moved.
"City and Liverpool are less than 40 miles apart and there are plenty of grounds big enough far closer than Wembley to stage such a prestigious game," they added.
