Arsenal's potential deal for Valencia defender Shkodran Mustafi is said to be stalling as the club cannot agree on a fee for the German defender, according to sources from BBC Sport.
David Ornstein, a BBC journalist who regularly tweets accurate transfer information about the Gunners, has tweeted saying the clubs cannot agree on a price and that Arsenal are considering alternative purchases.
The situation surrounding Mustafi has been shrouded in mystery over the last few days, and it seems as if the deal, that many fans of the club hoped for, may not happen.

Arsenal's need for a new experienced centre-half was made ever more apparent in Sunday's 4-3 defeat at home to Jurgen Klopp's Liverpool.
Arsene Wenger was forced to field a raw and inexperienced centre-back partnership in Rob Holding and Calum Chambers, leading to a barrage of criticism.

Liverpool took advantage and punished Arsenal; the void left by absentees Per Mertesacker, Laurent Koscielny and Gabriel Paulista was devastatingly apparent.
Now, it seems as if the club may be backtracking on signing a player they obviously need. Mustafi would be the perfect option to come into the squad and help revitalise a broken defence.
The 24-year-old was the standout player at Valencia last season, despite the club having a poor season, and is a regular in the German national squad.
Omer Toprak and Simon Kjaer, the duo mentioned by Ornstein, are both viable options too, but in the current climate, Mustafi would perhaps be the best option, one which seems logical for both player and Arsenal.
The only positive to be taken from the news is the club are preparing to potentially bring in a big money striker, something else which the Gunners desperately crave, especially after failed pursuits for both Jamie Vardy and Alexandre Lacazette.
Questions still remain over who the club are targeting in this area, but if they are setting aside funds for an offensive arrival, it would seem they are looking at some big-name players.
However, their lack of firepower up front should not disguise their need for a centre-back. Mustafi seems keen on the move and the right amount of money, which the club certainly possesses, would allow the transfer to come to fruition.
Arsenal need to sign more than ever, so monitoring their transfer progress over the coming days before the window deadline could make for entertaining viewing.
