The Premier League title this season is not yet impossible for Arsenal, but it is Chelsea who hold all the cards.
Jose Mourinho's side are seven points clear with a game in hand over the Gunners, and realistically it is theirs to lose.
With the international break upon us, it is the time for manager Arsene Wenger to begin planning his moves for the summer. Arsenal's squad is not far off being at the level required to compete, but instead tweaking is needed to ensure they have strength in depth throughout the team.
Here is a look at five players they should target to ignite a title challenge for 2015/16:
Francis Coquelin has been a real find for Arsenal in the defensive midfield position, but assuming him to be an answer on his own next season could be a critical error. The 23-year-old needs support to keep him fresh, and a more experienced head like Lars Bender would be the perfect signing. Bender, 25, is a German international who was linked to the Gunners in The Mirror just last month and his prolific tackling makes him an ideal fit for the Premier League.
French attacker Alexandre Lacazette has been outstanding for Lyon this season, scoring a phenomenal 27 goals in 26 games for the club. Only 23, he is going to be in demand and the French side will not sell easily, but he looks like the finished article that would complement Arsenal's attack perfectly. Able to play up front as a main striker, Lacazette can also play out wide, and could yet strike up a partnership with Olivier Giroud for club and country.
Arsenal are scouting Charles Aranguiz according to Chilean website PrensaFutbol, and the 25-year-old would be a smart addition. The Internacional midfielder shares the same agent as Alexis Sanchez, and could help his Chile teammate kick onto even greater performances. Aranguiz himself is a box to box midfielder who could come in particularly useful considering the injury issues Aaron Ramsey has had this season.
Vietto and Lacazette, that's just greedy right, but why not if Arsenal have the cash to spend? Vietto has been the find of the La Liga season for Villareal, scoring 18 goals in 36 appearances. At only 21-years-old, the Argentine is an outstanding prospect and one who is picking up valuable experience. Arsenal could throw Joel Campbell into the deal permanently to try and smooth it along, and allow Vietto to join up with Gabriel Paulista who made the switch in January.
Arsenal may have signed Paulista, but the need for further defensive reinforcements can't be ignored. Benedikt Howedes is one of the best players they could look to sign, a defender who can play at centre-back or at left-back. He is an international teammate of Mesut Ozil and Per Mertesacker, and a player who Arsenal were reported by The Mail to be scouting earlier this year.
