Few historical Premier League sides could have matched Jose Mourinho's Chelsea last season.
With world-class quality and incredible variety in everyone position, their startling squad is what every team aspires to attain.
One team that is on the verge of that is Arsenal. With arguably the most lucrative options for creative players in the league, the addition of a few players in key positions could really help them sustain a consistent title fight.

However, we know Arsene Wenger can be over-reliant on his current options and may choose to put the chequebook away after sealing the signature of Petr Cech.
So here we will run through the positions Arsenal need to strengthen and look at realistic targets that Wenger could potentially bid for.

Arsenal's current options in the centre of their defence are Laurent Koscielny, Per Mertesacker, Gabriel Paulista and Calum Chambers.
With Mertesacker clearly on the decline and Wenger still not aware of what position he decides to temporarily deploy Chambers in, one or maybe even two centre-backs are a necessity.
A realistic option for Wenger could be Lyon's young star Samuel Umtiti, who very much fits into the Frenchman's calibre of defenders as he is tall, strong and comfortable in possession; maybe something Mertesacker lacks.
Further possibilities could be Aymeric Laporte from Athletic Bilbao or, even though less likely, World Cup winner Mats Hummels.
Although Francis Coquelin changed Arsenal's season when he returned from his loan in mid-December, there is a feeling that they are one man light in the department.
With Abou Diaby leaving after an injury-plagued stay with the Gunners, a replacement is needed, not that Diaby provided much competition anyway due to his continuous injuries.
Two more that are unreliable defensive-midfielders are the ageing duo of Mathieu Flamini and club captain Mikel Arteta; it is fair to say that the pair are past their prime.
Potential defensive-midfielders that could come in to support and take the pressure off of Coquelin could be Southampton's Morgan Schneiderlin, the promising William Carvalho from Sporting Lisbon, or Bayer Leverkusen's Lars Bender, who Arsenal have had a long-standing interest in.
Despite the fact that Olivier Giroud does a good job, to take Arsenal to the next level they need a world class No.9 who is going to score over 20 goals a season.
Two words: Alexandre Lacazette.
With 27 goals in only 31 league appearances, he could may well be the striker to finally replace the Fenerbahce-bound Robin van Persie, who is in fact the last Arsenal player to score over 20 league goals in a single season.
As we've seen this season and over the years, Danny Welbeck and Theo Walcott aren't consistent enough to lead the line for the Gunners; and you can just forget about Yaya Sanogo.
The signing of Lacazette from Ligue 1 runners-up Lyon would be a real statement of intent from the north London club and could strike fear into the hearts of Chelsea fans.
