Arsenal set to confirm fourth summer signing, medical done

Arsenal are set to confirm their fourth signing of the summer transfer window with midfielder Bruno Guimaraes having undergone his medical tests.

The Gunners agreed a package worth £75m to sign the 28-year-old yesterday, and he has since flown to London to complete his medical successfully.

The midfielder has also put pen to paper on a four-year contract, and he is expected to be formally confirmed as a new player in the next 24 hours.

Guimaraes is set to become the club's fourth acquisition of the transfer window after Piero Hincapie (loan-to-buy option), Illan Meslier and Christos Tzolis.

The Gunners are expected to make more signings before the transfer deadline. A marquee left winger remains one of the top priorities for the hierarchy.

The club are likewise keen on landing a central defender, having witnessed William Saliba sustain a back injury during France's World Cup semi-final vs Spain.

Arsenal are yet to make formal bids for any other player.
