According to the Daily Mail, Mikel Arteta’s recruitment team has stepped up its transfer activity by making direct contact with the Brazilian’s camp, identifying him as a key target ahead of the new season.
The 28-year-old Brazil international, currently away on international duty, is one of Arsenal’s primary objectives as they look to add more control to their midfield.
Newcastle are understood to be aware of growing interest from top clubs and are preparing for a possible formal approach.
Although Guimaraes still has two years left on his contract at St James’ Park, Arsenal’s status as Premier League champions could influence any decision should a significant offer be made.
The midfielder has been a standout performer since joining from Lyon and remains central to Newcastle’s plans, but Arsenal’s interest signals a potential high-profile summer battle.
