Just when Arsenal's fortunes looked set to change for the better, they've been dealt yet another significant blow.
Shkodran Mustafi has reportedly agreed terms ahead of a potential £25 million move - which is great news - but reports now claim the Gunners face a battle to tie Mesut Ozil and Alexis Sanchez down to new contracts.
According to the Times, Arsenal will have to wait until the conclusion of the summer transfer window before re-entering negotiations with their star duo.

Such uncertainty will be a cause for concern for manager Arsene Wenger, who is under enough pressure as it is.
And it would seem Ozil's future is most in doubt after German newspaper Bild claimed he would jump at the chance to re-sign for Real Madrid.
In a loose translation, they state: "Ozil's heart is in Real Madrid, where he played from 2010 until his move to London, 2013.
"Should there be a chance to return, Ozil would join immediately."
Bild claim Ozil's apparent willingness to leave Arsenal for Madrid stems from his frustration at a lack of transfer activity in north London.
And you can hardly blame him considering how little Arsene Wenger has spent this summer in comparison to his Premier League rivals.
Whilst the Frenchman has forked out a meagre £34 million, Antonio Conte (£71m), Jurgen Klopp (£79m), Pep Guardiola (£146m) and Jose Mourinho (£156m) have all spent anywhere between double and five times that amount.
Arsenal's summer of spending could be about to breach the £50 million mark, though.
According to Sky Sports, the Gunners have agreed personal terms with Mustafi with a transfer fee left to negotiate.
Valencia want £30 million for the Germany centre-back but it's believed an opening offer of £20 million has been made.
A deal in the region of £25 million is most likely.
Signing Mustafi would go some way towards appeasing the seemingly 'frustrated' Ozil, especially considering the pair play together at international level.
Better still, Arsenal are reportedly keen to sign Riyad Mahrez from Leicester City having lodged a €41 million bid on Wednesday.
Predictably, their offer was rejected, but the approach serves to suggest that Wenger is indeed ready to spend big.
