During transfer windows, football fans concentrate their thoughts on which players their club should sign.
For Arsenal supporters, the summer transfer window is becoming a pretty stressful couple of months. Last year, Arsene Wenger failed to sign a single outfield player during the off-season - something that may have ultimately cost them in their failed title challenge.
This year, the Frenchman waited until the final few days to add to the £30 million signing of Granit Xhaka. He may have signed Rob Holding and Takuma Asano in the meantime, but those two players weren’t brought in to play regular first-team football this season.

But Wenger eventually splashed the cash, signing Shkodran Mustafi and Lucas Perez for a combined £52 million.
But Arsenal supporters shouldn’t just concentrate on who arrived at the Emirates this summer. They should also identify the players that remained in north London.

Both Alexis Sanchez and Mesut Ozil, unsurprisingly, attracted interest during this transfer window but Wenger managed to keep hold of the two world-class talents.
However, If the Gunners fail to produce a serious title challenge this season, it could well be the final season that both Sanchez and Ozil play together in the same Arsenal side.
Question marks certainly surrounded Ozil's future towards the end of the season after he admitted that contract talks had stalled ahead of Euro 2016.
Although the midfielder has now admitted that negotiations have begun again, he didn’t hide his desire to return to Germany - or even playing in the MLS.
Ozil on his future
"I have a contract until 2018. We have had discussions, but they were suspended for the European Championship,” he told German newspaper Express, as per Goal.
"I wanted to focus at this time only on the national team. Now we look to continue the negotiations.
"In football, you can never say never. You don't know what will happen. I had a good time in Germany. That was a lot of fun.
"Eventually [moving to America] could be an option. I have fun everywhere. My fans know that I like to spend my vacation in Los Angeles, because the city inspires me."
Ozil is now entering his fourth year at Arsenal and only has two FA Cups to show for it. If Arsenal can’t win their first Premier League trophy since 2004, then don’t be surprised to see some top European clubs trying to convince the talented playmaker to leave the Gunners.
