Arsenal just love to make things complicated, don't they?
Following an underwhelming summer transfer window and disappointing defeat to Liverpool on the opening day of the new Premier League season, the Gunners are desperate for new faces.
It would seem Arsene Wenger is busy trying to achieve just that yet the Frenchman still hasn't made a signficant signing since Granit Xhaka's arrival from Borussia Monchengladbach in May.

This is despite having agreed to personal terms with Valencia's Shkodran Mustafi.
Reports last week suggested a deal was in the offing, subject to a transfer fee, but the 24-year-old appears no closer to a move to the Emirates Stadium.
'But why hasn't he signed yet?' I hear you asking. 'What could possibly be standing in Arsenal's way?'
Well, there's a very simple - and extremely frustrating - answer to that: money.
Yes, Wenger's tight approach to the transfer market is once again on show amidst a reluctance to meet Valencia's £30 million asking price.
According to the Daily Mail, Arsenal are holding firm on £20 million and refusing to go above that fee because of their valuation.
Talks between the two clubs are ongoing but the fact remains that Mustafi's employers are unwilling to budge; if Arsenal want the German, they must cough up.
What's certain is Wenger needs to make a quick decision after losing 4-3 to Liverpool on Sunday.
Whilst exciting prospects, Rob Holding and Calum Chambers lack the experience to start at the back for a club of Arsenal's size.
The pair's frailties were exposed on one too many occasions against Jurgen Klopp's men, with Philippe Coutinho, Roberto Firmino and Sadio Mane running riot in the second half.
Indeed, Mane's goal was made possible by Chambers' lack of pace, even if his finish was fantastic.
Were it Laurent Koscielny and Mustafi at the heart of defence against Liverpool, the end result would have likely been very different.
Arsenal take on Leicester City on Saturday and, should they fail to complete a deal for Mustafi in time, they risk being torn apart by the likes of Jamie Vardy, Riyad Mahrez and Ahmed Musa.
