Swansea manager Brendan Rodgers insists the pressure will be on Premier League champions Manchester United when they visit the Liberty Stadium on Saturday.
The Swans are currently 10th in the Premier League and are unbeaten at home this season.
Second-placed United will start as favourites, but Rodgers says the pressure will be on the visitors.
"If you invest millions of pounds into a team then these are games they should win," he said.
"When you are at a big club you are judged on the big games, because these are the games you should win.
"They won't have any fear of coming here, that's why they are at that level.
"It's a fantastic game for us. In the big games we are the underdog but we arrive in the game with confidence and belief that, if we play to our maximum, we can get a result.
"It will be an incredible atmosphere. It's an early evening kick-off and it will feel like there are 50,000 in the stadium.
"So with that and our qualities we will try to exploit that if they have an off day."
Northern Ireland-born Rodgers had a spell as a trialist at United early in Sir Alex Ferguson's reign at Old Trafford.
And Rodgers has hailed the Scotsman, who recently celebrated his 25th anniversary at United.
"He is a wonderful inspiration to young managers like myself, and he is the boss of all managers, he has a great hunger and ambition to achieve and remain at the top," he said.
"You have to admire how he has managed change over the last 20-odd years.
"When I was going there as a 14-year-old in 1987 they were talking about moving from the Cliff training ground, which had so many big traditions and had seen so many great players.
"Yet he managed to do that and retain the ideals of the club.
"The way he has adapted with the game, but retained the class and morals is what has kept the club successful."
Left-back Neil Taylor, who suffered an ankle injury during the 0-0 draw against Liverpool, is fit again while winger Scott Sinclair is also back to full fitness.
On-loan Spurs defender Steven Caulker will again miss out as the game comes just too soon for him to return from the knee injury he picked up against Arsenal in September.
Midfielder Kemy Agustien will be part of the squad after making his comeback following a hamstring injury as a late substitute against Liverpool.
