The United captain will lead the Magpies out onto Wembley Stadium this weekend ahead of the club's second Carabao Cup final in their last three seasons, aiming to create history by ending a 70-year wait for a domestic trophy.
Guimarães is fully determined to extinguish Newcastle's lengthy drought for major silverware and, visibly upset following the 2023 final loss at the hands of Manchester United, wants "tears of happiness this time".
The 27-year-old midfielder said: "Everyone knows how emotional I am and I always strive to give everything that I have on the pitch, to play as a fan because I know what it means for them.
"(I'm) feeling good. It's a good opportunity for ourselves. We cannot wait to get there and everyone is very excited, as a team and a city. We have worked very hard and, hopefully, everything will be good and we can get this trophy back to Newcastle.
"We know exactly what it means to the fans. It's a long time and we see this opportunity as a big one. We want to make everyone in the city happy. We have our targets as well and we have to play our game, nothing different, and hopefully everything would be good for us."
Conducting his pre-match media briefing alongside Alexander Isak at the Newcastle United Media Centre on Friday morning, the charismatic Brazilian believes the club are in a stronger position than their previous cup final ahead of facing Liverpool, who lifted the Carabao Cup last term and currently occupy top spot in the Premier League table.
"Now, we have more confidence and are different players," he added. "Our confidence is very high at the moment because it is a good opportunity to make history together.
"When you make a final before, you get more experience as a team. You change some players but the base is still there. We are in a better moment than the last time we faced Man U in the final so very confident and hopeful we can go there and play our best football. On our best day, we are a great team.
"We just want to make thousands and thousands of Geordies happy. We know football, sometimes, can attack you in every way but our message is stay positive. We are going to do our best to get this trophy back to the city."
Guimarães will be hoping to follow in the footsteps of a handful of former United skippers to lift a piece of major silverware, including the likes of Joe Harvey, Jimmy Scoular and Bob Moncur, the latter doing so in 1969 as the Magpies won the Inter-Cities Fairs Cup.
The Rio de Janeiro-born midfielder also revealed he has been in discussions with Rob Lee, the last Newcastle player to score at Wembley Stadium after netting in the 2000 FA Cup semi-final defeat against Chelsea, and even "rubbed his feet to give me a bit of luck" but is hopeful of etching his own name into the club's 133-year history.
"Seventy years is too much but, of course, when you see the club's history you will find those names there," he said. "We want to be there as well. I just want to play well and win the trophy.
"You don't wish them (the fans) to go through this moment but we are seeing this as a big opportunity to make history after a long time. We know the excitement of the fans but we try to not get focussed about what they are thinking.
"You cannot think too much about that time. We want to be focussed on the job and play our best game."
