Harry Redknapp has admitted it will be hard for Queens Park Rangers to hold on to Loic Remy if they go down.
QPR look set to be relegated as they head into Saturday's clash with Everton still seven points adrift of safety, with just six games of the campaign remaining.
Remy has nevertheless impressed since arriving from Marseille in January, and Redknapp believes he would be among the Premier League's leading scorers if he had been with the club all season.
Redknapp concedes that a player of such quality is unlikely to stay ay Loftus Road if they drop into the Championship, although no talks have yet taken place as everyone focuses on the fight for survival.
"I would have thought it would be hard to hang on to Remy. He was someone we were chasing when I was at Spurs," said the QPR boss.
"Every goal he has scored here has been a fantastic goal. He has five goals in seven games.
"Over the season he would get you 20 goals in the Premier League. And a 20-goal-a-year man is going to be hard to hang on to.
"We have to make sure we stay up if we want to keep him. That's the key, although I haven't discussed it with him or the owners."
McManaman estimates he will have an 80-strong support for the encounter with Millwall at Wembley, all hoping McManaman can retain his place in Roberto Martinez's starting line-up.
"I can't wait for Saturday, " the 22-year-old told Wigan's official website.
"I've got 55 of my mates going on a coach and 25 of my family members will be there as well, so it's quite a big following.
"If I play it will be the biggest game of my career."
It is Wigan's first appearance at the last four stage of the competition and victory would open the door to Europe should both potential final opponents, Chelsea and Manchester City, qualify for the Champions League.
Not that McManaman is unused to the experience given his family are all Evertonians.
However, the Merseysider owes a debt of gratitude to the competition because it was Martinez's desire to use it to blood youngsters during the early stages that offered him a chance to shine.
"When we started the cup campaign against Bournemouth I wasn't playing very well and I started to get a bit frustrated because I wasn't fully fit and hadn't been playing many games," he said.
"It all changed in the fourth round at Macclesfield. That's where I turned around my form personally and as a team we've just kicked on from there."
With a fully fit squad to choose from and seven points from the last three Premier League games, Wigan can approach their task with confidence, knowing it will be a special day for chairman Dave Whelan, who broke his leg in the 1960 FA Cup final.
"It will be a significant day for the chairman because he has been through such a lot," said the Wigan manager.
"The FA Cup is something very special for him.
"Not many people had the experience he did in the 60s, with the final and being carried off.
"There is a sense of unfinished business. It is a unique way of closing that circle."
The Lions midfielder has had to make regular trips back to France this season to spend time with his four-year-old son, Llyas, who has leukaemia.
And the 28-year-old claims he will be using his son as motivation for the Wembley semi-final.
"He's had leukaemia for about nine months and is having treatment, he's doing well and hopefully he's going to get well again," Abdou said.
"My strength is my son. When I see he is doing well I follow him, and hopefully we are going to get through it.
"He will be watching the game on Saturday so he'll be happy to see dad on the TV hopefully.
"The club and the manager have been brilliant, I can go back any time I need to.
"It's difficult, but when I'm here to do my job I give 100 per cent. You have problems in your life and you have to deal with them.
"When you play football for 90 minutes you have to switch off but when I finish the game the first thing I do is call home to see what's happening.
"When I go home and see him smiling and happy that's the main thing."
Whyte was last week reported to be planning legal action in an attempt to regain control of the club's assets, claiming he was the main driver behind the Sevco 5088 company which purchased the assets and business of the company he had put into administration.
Days later, Green transferred the assets - which were bought for ?5.5million in June last year - to a different company called Sevco Scotland, which then became The Rangers Football Club.
In angrily dismissing Whyte's claims last week, Green said: "It is alleged there is a letter which agrees Mr Whyte and a business partner of his, Aidan Earley, would have a majority shareholding in Sevco 5088. If there is it wasn't signed or endorsed by me."
A report on STV on Friday evening showed what appeared to be documentation confirming Whyte as a company director of Sevco 5088.
But in the latest salvo in the war of words between the two men, Green issued a fresh statement denying the validity of the paperwork shown.
The statement, on Rangers' official website, read: "Mr Green is appalled by this blatant attempt to discredit him.
"These documents are not correct or valid and he did not sign Craig Whyte or his associate on as directors of Sevco 5088.
"Mr Green was the sole director of Sevco 5088 until he resigned and became the founder director of Sevco Scotland, formed by Scottish solicitors.
"If this documentation was correct then, as Sevco 5088 was formed as the initial bid vehicle, the administrators would have been negotiating a sale of the club to a company which had a director who was clearly forbidden from being involved with it.
"Furthermore, it should strike people as deeply suspicious that these documents are being filed today 11 months after they were supposedly signed and on other documents Mr Green's home address has been mysteriously changed without his knowledge.
"Furthermore, notice was filed publicly in January this year by Field Fisher Waterhouse and is on record at Companies House company seeking to strike off the company, yet four months later directors appointments are now being supposedly filed.
"As stated previously these matters are now in the hands of lawyers who are preparing a file to be sent to Police Scotland and Mr Green cannot comment further on the details of that process."
