We are approaching the time of year that all Arsenal fans hate the most, the transfer window.

It'll be three months where the Gunners will undoubtably be linked with every single player on the planet, but here I take a look into the signing which Arsene Wenger must take into consideration in order to strengthen his squad and pose a real threat for the Premier League title next season.

After the way that this season panned out, it is clear that Wenger and Stan Kroenke must change their ways and have a less stubborn approach in the transfer market.

The Arsenal fans, as per usual, will be praying for the next Thierry Henry or Tony Adams, but based on recent years, they shouldn't raise their hopes. If Wenger does open his chequebook then here are the kind of players that he must sign.

A clinical striker

Pierre-Emerick Aubameyang

This will come as no great surprise, but it is absolutely vital that Arsenal sign a striker this summer.

Olivier Giroud and Theo Walcott are simply not of title-winning quality. Giroud's conversion rate is a mere 16%, so the likes of Pierre-Emerick Aubameyang or Robert Lewandowski would completely change the dynamic of Arsenal - they are the level of player that the Gunners must sign if they are serious title contenders.

A Back-up

The next big thing?

It may sound harsh, but considering the Arsenal strikers' records as well as their injury history, the club must be prepared for the worst.

If Arsenal splash out on a world-class striker, they must be cautious and prepared for the possibility of injury or suspension. If I was in Arsene Wenger's shoes, I would not be happy enough with Giroud, Walcott or even Welbeck on the bench. All three of them have a serious injury history and therefore I think Arsenal should turn to Breel Embolo. The 19-year-old has nine goals and seven assists in the Swiss league this season, and although he may be a gamble, he might be one worth taking.

A Leader

Xhak attack

Many people believe that Arsenal lack passion and leadership.

Francis Coquelin is often the only Arsenal man who looks as if he really cares about playing for the badge and for the fans. Arsenal need a leader on the pitch to motivate the team and encourage his team-mates when in a patch of poor form, which knowing Arsenal, is very likely to occur at some point.

Granit Xhaka is the perfect player for Arsenal. Not only is he a classy midfielder that suits Arsenal's style of play, he is an instrumental part of any team that he plays in. Amazingly, Xhaka is the captain of Borussia Monchengladbach at the age of just 23.

A centre back

Varane the man?

Varane would be an ideal man for Arsenal.

He is young, calm, composed, strong and great in the air. Per Mertesacker is now 31 and Laurent Koscielny is only a year younger whereas Varane is just 23. It may be difficult to tempt the Frenchman to leave the Bernebeau, but he would definitely be an incredible signing for the north Londoners. Despite his age, Varane is very experienced and would offer some much-needed security in front of Petr Cech's goal.

A commanding midfielder

First Ozil, now Isco?

Isco has not been getting enough game time for Real Madrid this season and will surely be evaluating his options in the summer.

Santi Cazorla and Jack Wilshere both missed large portions of the season due to injury, but even if they were fully fit, they would struggle to get into the side if a player of Isco's calibre was there too. Isco would bring goals, assists and composure to the Emirates Stadium.
