Arsenal boss Mikel Arteta is reportedly weighing up a sensational late swoop for Newcastle United midfielder Sandro Tonali.
With Mikel Merino ruled out for the remainder of the season after foot surgery, Arsenal are desperate for midfield reinforcements.
Newcastle have already rejected an initial enquiry, but reports from Germany suggest the Gunners could return with a club-record offer.
Arteta is said to be "disappointed" with the lack of mid-season business and sees Tonali as a potential game-changer for the title race.
