It has been a season of very few positives for Arsenal so far, with the Gunners already suffering a number of setbacks in the Premier League.Losses to Liverpool, Stoke and Watford have pretty much ended any chance of challenging for the title, while star men Mesut Ozil and Alexis Sanchez look set to depart the club in the near future.But, there have been a few glimmers of hope, with the returning Jack Wilshere a real source of solace for supporters.After an impressive loan spell at Bournemouth, the England international looks like he is well on the road to rediscovering the form that made him one of the most sought-after players in world football.Arsene Wenger has used him sparingly, with the majority of his minutes coming in the Europa League, where he has certainly caught the eye.Against Red Star Belgrade, Wilshere was arguably the finest player on the pitch, playing a vital role in Olivier Giroud's match-winning goal in Serbia.He was given a cameo in the 5-2 win over Everton and was then handed a start by Wenger in the Carabao Cup tie against Norwich.However, against the Championship side, Wilshere was far from his best, with his personal highlight reel from the game looking far from impressive.

WILSHERE'S HIGHLIGHTS

It was something of a reality check for Wilshere, who looked rusty and out of ideas against a stubborn Canaries side.

Arsenal fans on Twitter were not happy with the performance and voiced their concern on the social media platform.

ARSENAL FANS REACT

To be fair Wilshere was far from the only Arsenal player to turn in a woeful performance, with Alex Iwobi, Olivier Giroud, Francis Coquelin and Theo Walcott all below-par.

Strangely, Wenger opted for a bizarre formation which saw Iwobi as a deep-lying central midfielder, while Wilshere was deployed on the left of attack.

Surely, given both players natural style, the roles should have been altered.

The hero of the night was young striker Eddie Nketiah, with the 18-year-old coming off the bench to score two goals.

WENGER IMPRESSED WITH NKETIAH

"I don't know what happened at Chelsea," Wenger told reporters after the game. "He has scored goals at youth level and sometimes I don't know why they let him go.

"I don't know why. You see that more and more. Young people travel from one club to another. I don't know.

"He has top quality and is one of player who was with me in pre-season and I knew what he could do.

"I must say I am impressed when I think he was not even conceived when I was already here [became Arsenal manager].

"But it is good as well. Life gives a chance to young people and hopefully he will make a long career at Arsenal. We are proud to give young players a chance."
