Jack Wilshere's career appears to have once again stagnated following his return to Arsenal from a season-long loan move at Bournemouth.A lower leg fracture suffered against Tottenham back in April saw the 25-year-old's season cut short and also put his future in jeopardy.He has since recovered, but initial signs suggest he faces an uphill battle to work his way back into Arsene Wenger's side.Wilshere played for Arsenal Under-23s against Manchester City earlier this month and humiliated himself when he received a straight red card for pushing two players.At the age of 25, Wilshere knows he shouldn't be getting into fights with players much younger than him and clearly still needs to work on his discipline.Wenger was oddly forgiving, though, saying: "He should not have responded, but when you have gone through what he has gone through, it was a human reaction."He is working very hard to come back, another setback for him would be terrible. I love Jack and his talent."Rumours then began to circulate towards the end of the summer transfer window that a loan move to Birmingham City in the Championship could be on the cards.Nothing transpired, but joining Carl Jenkinson at Birmingham would have just about summed up the critical state of Wilshere's career.Arsenal fans are keen to see the Englishman reinstated this season, but his recent behaviour on social media hasn't gone down very well.A clearly frustrated Wilshere commented on Tyrone Mings' Instagram post about his academy on Friday night asking: "Do you take 25-years-olds who can't get a game? I'm fully fit and ready to go."

It's a pretty funny comment, in truth, but Arsenal fans don't really know what to make of it.

Some have found it hilarious, while others believe Wilshere is showing the attitude of a 'finished player' who needs more fight.

Wilshere still has huge potential and now even Wenger has called upon the England international to work hard and fight for a place.

"He has to work hard to come back and fight for a place in the team," said Wenger in July. "Once he is ready, when he comes back, he will not be far from practising with the team."
