Dusan Vlahovic's potential January transfer to Arsenal or Tottenham may have been complicated by a positive Covid-19 case for the striker.
The Serbian has been heavily linked with a move to both sides, with the Gunners said to be the favourites for the striker, having put him as their top transfer target this winter.
Mikel Arteta is said to be on the lookout for a new forward, with Alexandre Lacazette and Eddie Nketiah out-of-contract in the summer and Pierre-Emerick Aubameyang's future at the club no clearer.
