Arsenal must remain patient in their pursuit of Pierre-Emerick Aubameyang as the transfer hinges on Borussia Dortmund landing a replacement before allowing the striker to leave.
Press Association Sport understands a deal has been agreed in principle between the clubs, subject to Dortmund bringing in their own forward.
The German club have been linked with Gunners striker Olivier Giroud and Chelsea frontman Michy Batshuayi as possible replacements for the Gabon international.
One player Arsenal will not be signing before Wednesday’s 11pm deadline is Monaco midfielder Thomas Lemar.
The Ligue 1 champions’ vice-president Vadim Vasilyev has reiterated that the France international – also a reported target for Liverpool – is not for sale this month.
“He will stay at Monaco until the end of the season 100 per cent,” Vasilyev told French radio station RMC. “If Liverpool or Arsenal come with a big offer before the end of the market? This is not relevant.”
Leicester forward Ahmed Musa has re-joined CSKA Moscow on loan for the rest of the season.
