The French defender has not featured under Mikel Arteta since he arrived in north London following loan spell at Saint-Etienne, which came to an end a year after completing a £27million move to the Gunners.

Midfielder Guendouzi suffered a similar treatment last season and was exiled by Arteta over disciplinary reasons last season before being loaned out to Hertha Berlin during October’s deadline day.

Guendouzi scored his first Hertha on Saturday and shared images of his goal on Instagram, with reacting with the ‘fire emoji’ in the comments section.

Arsenal winger Nicolas Pepe, who has suffered from on-field disciplinary issues this season after his red card for violent conduct at , then commented: ‘This is your (Saliba’s) problem, you comment on everything.’

Saliba then jokingly replied: ‘Hahaha, I’m sending well wishes to the brother that was locked up like me.’

Guendouzi then gave sympathy to the Arsenal defender, saying: ‘We are together bro.’

This is the second time this week that Saliba has lifted the lid on his situation at Arsenal, after he questioned whether he is actually an Arsenal player to striker Alexandre Lacazette.

In a knowledge game for Arsenal’s official media channel, both Lacazette and the young defenderhad to name as many French footballers to have played for the Gunners, with the former putting Saliba as his answer.

That prompted an awkward response from the teenage defender, who claimed: ‘I haven’t played yet!’, while laughing.

Lacazette immediately answers back: ‘Of course. Oh, but you signed,’ before he starts laughing.

Lacazette asks: ‘Does Saliba count or no?’ to which Saliba replies: ‘No, because I didn’t play.’

And while Saliba – who joined as one for the future at the Emirates – is speaking, he starts covering his face with his hands.

Lacazette again replies: ‘But you signed for the club, it’s the same’, but Saliba continues his case: ‘No, no. He said French players.’

Saliba’s online outbursts come as reports claim he has ‘no chance’ of breaking into Mikel Arteta’s first-team plans, despite the Gunners suffering some defensive  injuries in recent months.

Pablo Mari, Shkodran Mustafi and Callum Chambers picked up long-term injuries last season and have only just returned, while David Luiz has also missed some games this term.

Sokratis Papastathopoulous has been exiled by Arteta as well having not been named in Arsenal’s 25-man squad for both the and the Europa League.

But according to Eurosport, the Arsenal manager believes Saliba is not ready yet and is ready to ship him out on another loan deal to give him more experience.

The 19-year-old is yet to play for the first-team but has played for the Under-23s in the past few weeks, most recently in a 3-0 Football League Trophy defeat to AFC Wimbledon where he was sent off for two yellow cards.
