The 27-year-old Brazilian midfielder, who has been a cornerstone of Newcastle's recent resurgence, is attracting significant interest from top clubs worldwide.
Since joining Newcastle as one of the first marquee signings after the Saudi-backed takeover, Guimaraes has quickly become a fan favourite on Tyneside.
He captained the Magpies throughout the entire Premier League campaign last season, leading them to Champions League qualification and playing a pivotal role in securing the club's first silverware in 70 years - delivering a standout performance against Liverpool at Wembley.
Internationally, Guimaraes has earned 35 caps for Brazil since his debut in 2020 and started every match in the 2024 Copa America.
Manchester City are currently the most seriously linked suitors, eyeing Guimaraes as a potential addition to bolster their already elite midfield.
Meanwhile, Saudi Pro League giants Al-Ittihad, owned by the same Public Investment Fund that controls Newcastle, have expressed interest by initiating contact with the player's agent. However, they have yet to submit an official bid.
