Arsenal could miss out on signing Barcelona's Denis Suarez after failing to agree a fee with the club.
The Gunners are prepared to sign the forward on loan this month with a view to a permanent move in the summer.
But they are only willing to pay £15million at the end of the season while Barcelona are demanding more.
Talks are continuing but hopes are fading that Arsenal can complete a move before next Thursday's deadline.
Suarez has been left out of Barcelona's squad for the first leg of their Copa del Rey quarter-final against Sevilla on Wednesday.
His place has been taken by Kevin Prince-Boateng after his loan move from Sassuolo.
Boateng - who sees himself as a forward these days - believes he can help aid Barcelona's treble bid.
