Alexis Sanchez staying at Arsenal should be great news, but huge concerns remain as to what the future holds.
According to various sources, Sanchez doesn't want to play for the Gunners and will seek a move to Manchester City in the winter transfer window.
City are similarly unimpressed by how Arsenal conducted themselves on transfer deadline day after they pulled the plug on Thomas Lemar's move, which would have allowed Sanchez to leave.
Arsenal and Monaco agreed a £92 million fee for the 21-year-old, but Arsene Wenger decided there wasn't enough time to complete a deal.
There were five hours remaining of the transfer window when Wenger pulled out of signing Lemar, suggesting he had more than enough time.
Wenger now faces a battle to get Sanchez back on his side following a frankly woeful start to the 2017/18 Premier League season.
Arsenal have lost two of their opening three games, most recently suffering embarrassment against Liverpool at Anfield.
It remains to be seen whether Wenger can patch things up with Sanchez and now Gary Neville has explained what must happen if Arsenal are to have any hope of salvaging their season.
According to the Sky Sports pundit, it's up to Sanchez to shrug off the disappointment of not joining City and rediscover his previous scintillating form.
"For Arsenal now, it's all about which Sanchez turns up," he said, "the terrier-type player that I look at and love, or the one in the last four or five months that throws the towel in and his hands in the air at his team-mates, which I do not like.
"He's been someone who has been difficult to warm to in the last few months, particularly at Anfield. Within the first 20 minutes after the first goal, he was throwing his arms up at his team-mates.
"And when players start doing that, then you have big problems, especially when it is coming from a star player."
Neville adds that if Sanchez and his Arsenal teammates can find a way to work together, they have the talent to "destroy" teams.
"It will be interesting to see what Sanchez turns up over the next few weeks," Neville continued.
"You look at their forward line now - [Mesut] Ozil, Sanchez, [Danny] Welbeck, [Alexandre] Lacazette and [Olivier] Giroud - that is an absolutely outstanding forward line who should destroy teams.
"They should score a bag full of goals every single game - we know they have issues in central midfield and can defend better, but if those players decide they want to perform and play, then they have a chance of having a good season.
"But it depends what attitude they have when they turn up for training. Arsene Wenger's first day back after international duty is a big one.
"He has to grip them by the scruff of the neck and somehow inspire them to play how they can. Rumours starting circulating this week that the players wanted him out - that's the biggest issue."
