The Christmas season is upon us, and with it comes the halfway point of the 2017/18 campaign in the Premier League.
Arsenal fans were initially optimistic, with a deal for Bundesliga left-back of the year Sead Kolasinac wrapped up on the first of July, followed by the acquisition of Lyon's superstar striker Alexandre Lacazette for a record fee.
However the window quickly descended all too familiarly, as Wenger failed to strengthen essential parts of the team with the aforementioned duo being the only summer signings of 2017.
At the midway point of this term, just how have both stars fared at the Emirates and what is needed in the upcoming January window?
4. Sead Kolasinac
Sead Kolasinac is everything Arsenal fans were crying out for: a non-passive, passionate player that puts everything on the line for the badge and possesses a serious physical presence in the Gunners' rearguard.
The Bosnian international's arrival seemed to provide Wenger's side with better balance, as Nacho Monreal was allowed to return to his preferred role of left-centre-back from left-wing-back.
The only thing that seems to be currently hindering the 24-year-old's progress this season at the Emirates is the frequency of injuries. Kolasinac's aggressive front foot defending means he often suffers with impact injuries and it now looks as though he will miss Arsenal's vital upcoming clash against Chelsea - in pursuit of top four in England's top flight.
3. Alexandre Lacazette
Before moving to north London, Lacazette probably dreamed of titles in the Premier League and spear-heading his side to higher levels. Thus far, the only title becoming his own is the unwanted accolade of being the top flight's most substituted player.
In 17 starts under Arsene Wenger, the former Lyon superstar has been brought off in 14 of them. No player has been hauled off more this campaign and fans are becoming seriously bemused at the lack of playing time for their record signing.
The 26-year-old is 20 games into his Premier League career and has had a hand in 11 goals - scoring eight and assisting three. Maybe next season after the inevitable departure of Alexis Sanchez we will see the best of the promising striker.
2. January Target: Fabinho
Midfield enforcer Fabinho was a vital cog in a Monaco machine that dominated Ligue 1 and reached the semi-finals of the Champions League last season - proving too much for the likes of Manchester City and Borussia Dortmund.
The Brazilian was directly involved in 14 goals in all competitions in 2016/17 netting ten and assisting four.
It's no secret that Arsenal are in dire need of a quality ball-winning central midfielder and Fabinho is the best of the bunch in terms of realistic January targets for that position.
1. January Target: Thomas Lemar

Arsenal simply need a winger that follows the old mantra: "get chalk on your boots."
Fans are becoming irked with their team's recently-languid and uninventive play through the centre of the park with little penetration or width and the signature of Thomas Lemar would go a long way to rectifying this.
Sanchez looks to be on his way out in the summer and it's likely Wenger will wait until the Chilean's future is resolved to think about a replacement. However, the club may need to invest in forward positions earlier if they're to secure a hotly-contested Champions League spot for next season.
