Bruno Guimarães was absent from Newcastle United’s flight to their pre-season camp in Spain, intensifying speculation over a potential move to Arsenal. His future is likely to be an early priority for incoming head coach Matthias Jaissle, whose appointment follows Eddie Howe’s departure and signals a wider period of upheaval at the club.

Guimarães is due to fly to Spain on Sunday, but could instead travel to London if Arsenal make an offer of about £75m. Newcastle have reportedly agreed an £8m compensation package with Al-Ahli for Jaissle, while they are also considering other possible departures and expect to complete a £26m deal for Braga goalkeeper Lukas Hornicek.
