The Brazil international midfielder enjoyed a superb month after scoring his first goal for his country at the end of March, as he helped Newcastle United to win four of their six matches.
He scored three times - a double against Leicester City and a glorious chip at Norwich - and claimed an assist for Miguel Almirón's winner against Crystal Palace, with his form also seeing him nominated for the Premier League's EA Sports Player of the Month. Voting for that award is still open here.
For the club's FUN88 Player of the Month award, Guimarães got an astonishing 80 per cent of the supporters' vote.
Emil Krafth was the runner-up with 10 per cent of the vote, with Joelinton and Matt Targett in third and fourth place respectively.
Guimarães said: "Thank you, Newcastle fans. Thank you for voting for me.
"I'm so happy here. We are together. Come on Toon!".
