Arsenal have officially announced the signing of Brazilian midfielder Bruno Guimaraes on Saturday morning. The 28-year-old joins the club in a transfer that makes him the most expensive midfielder over 26 ever signed, according to reports. He will wear the number 39 shirt at the Emirates. Guimaraes previously faced Arsenal in a fiery clash at St James' Park in 2023, a match that highlighted his combative style against the Gunners. The move is seen as a major reinforcement for Arsenal's midfield as they continue to strengthen their squad. No further details of the transfer fee or contract length have been disclosed by the club.
