WIGAN boss Roberto Martinez has claimed Saturday's FA Cup semi-final at Wembley will feel like a home game for Millwall, with the Latics failing to sell 10,000 tickets.
The Premier League club have fallen well short of selling out their allocation and, as a result, the FA have taken the unusual step of making seats available for neutrals.
The Lions have played twice at the new Wembley since it opened in 2007 and Martinez said: "We've never been this far in the competition and it's going to be a tough day for us.
"Wembley will be like playing at home for Millwall. They will have huge support and have played at Wembley two times in the last few seasons in play-off finals."
However, Lions defender Alan Dunne does not think the gulf in support will make a difference. He said: "It won't feel like we're at home. Wigan are used to playing in front of big crowds.
"They play in big stadiums every week and they have international players so I do not think that will be a factor in the game. It's a long way for their fans to come down.
"It is expensive to get a train down and stay in a hotel. They work hard all week just to see Wigan on a Saturday so I can see why they've only sold 20,000 tickets.
"But 30,000 Millwall fans will sound like 50,000 on the day."
