The Red Devils have not always showcased their attacking prowess this season, with Jose Mourinho having been accused of favouring a more defensive mindset.
The Portuguese does, however, have enough firepower at his disposal to worry the best in the business, with the FA Cup final providing a perfect stage on which to release the shackles.
Giggs is hoping to see star men shine at Wembley Stadium on Saturday, with United looking for their most creative influences to counter the threat posed by the likes of Eden Hazard and Willian.
The Red Devils legend told MUTV: “It is an important day because coming second in the Premier League and winning the FA Cup is a successful season.
“You always want to end the season with a trophy because it gives you a good feeling over the summer and you can't wait to get back for next year.
“It is important and Manchester United is all about winning trophies. Once you get to cup finals, a club like Manchester United is under pressure to win it. But it won't be easy because Chelsea are in the same boat. Their season will be defined by the result.
“I think it is a 50/50 game because these are two teams with special players who can win it for them in a moment.
“There are also two very good managers so it's really 50/50. It's about who turns up on the day. It will define the two clubs' seasons so there is a lot of pressure on the game.
“If you can keep Eden Hazard quiet then I always think you have a great chance against Chelsea. Of course, Willian is a special player as well, so if you can keep both them quiet then you have a chance.
“United have some special players as well. Marcus Rashford scored at the weekend, Alexis Sanchez is coming into form and starting to look good, and we're hoping Romelu Lukaku can make the final. It will be won and lost with the special players. Those forwards can make the difference.”
