This year's Premier League title looks set to go right down to the wire once again, with Chelsea, Manchester City, Arsenal, Liverpool and Manchester United all bringing in solid additions over the summer.
The bookmakers have made Chelsea favourites to win the title, trailed by City, United, Arsenal and Liverpool respectively. But should Arsenal be backed at shorter odds? Yes. Here's why.
Last year Arsenal finished just seven points behind champions City, despite long term injuries to key players such as Aaron Ramsey, Mesut Ozil and Theo Walcott among others. Arsene Wenger has set about rectifying this with the arrival of Germany's World Cup fitness coach Shad Forsythe.
Forsythe managed to keep Germany's superstars playing frequently after a long season, to great success. If Arsenal can keep key stars fit, those seven points might be easy to make up.
Finally, Arsene Wenger has learned his lesson and got his chequebook out early. Mathieu Debuchy, David Ospina, prospect Callum Chambers and most excitingly, Alexis Sánchez, have arrived to replace outgoings and strengthen the team.
Arsenal's main problem last year was a lack of pace in Theo Walcott's absence, leading partly to Ozil's drop in form. The signing of Alexis will not only boost the team, but get the best out of Arsenal's record signing.
Arsenal finally ended their trophy drought in May by winning the FA Cup, and followed that up by beating City in the Community Shield in August. This will give confidence to Arsenal much in the same way City's 2011 FA Cup win gave them the confidence to win the title. The Gunners now have players who have experienced going all the way and winning, which will benefit them greatly this season when the going gets tough.
Arsenal have been slightly under rated by the bookmakers this summer. While it is easy to note the strengths of their rivals, it must be remembered how strong Wenger's side are as well.
