Negotiations between Arsenal and Barcelona over the signing of Gunners forward Pierre-Emerick Aubameyang have broken down.
But Barcelona are understood to still be interested in a deal for the Gabon striker before the window closes.
Aubameyang, 32, flew out to Spain to have a medical as he looked to complete a move to the Catalan side until the end of the season.
He has not played for Arsenal since a disciplinary breach in December.
Aubameyang, who had been linked with a switch to Saudi Arabian side Al-Nassr, landed in Spain on Monday.
If Aubameyang departs, it will leave Gunners boss Mikel Arteta with just Alexandre Lacazette and Eddie Nketiah as his forwards for the remainder of the season.
Aubameyang was sent home early from the Africa Cup of Nations in January because of ongoing health issues.
The striker missed Gabon’s draw with Ghana after scans revealed “heart lesions” following a bout of Covid, although later scans gave him the all-clear.
