Leighton Baines believes Everton are playing well enough to capitalise on a possible Manchester United 'dip' at Wembley on Sunday.
The Toffees have already beaten Liverpool, Aston Villa and Middlesbrough on their way to the semi-finals of the FA Cup.
They have managed to maintain a push for Europe in the Premier League and Baines has been encouraged by their recent form.
The defender has also noticed that United have been less convincing than earlier in the season and feels Everton can take advantage and make it through to the final.
"We have got to believe that this tie gives us the chance of an upset. We fancy our chances," said Baines.
"We have been scoring a lot of goals of late and United maybe have hit something of a dip at the moment in their form.
"So hopefully that will work in our favour. We have to get into their faces, we have to do that against a side as good as Manchester United.
"We have to put them under as much pressure as we can and make it difficult for them to play the game they want.
"Once we have done that it will give us the chance to start getting at them. But we must make it as tough as we can for them."
Baines accepts it will still be extremely difficult for Everton against a United side that has incredible strength in depth.
He explained: "They have players you expect to be in the side and they don't even get onto the bench.
"You sometimes even wonder if they know what their best side is at times. They have so many good players and can come up with a whole range of variations.
"They are a bit special, a bit different to everyone else. But we have done well against them and we can do it again."
Baines added: "This semi-final is a dream for me, and it is at Wembley which adds a bit of spice for us all.
"This is the chance to get this club into a cup final, it has been too long since we have been there.
"People do feel the game should not be at Wembley because it takes something away from the final, but on the other hand, it is a great occasion and a chance to play there."
