Arsenal reverted to type on transfer deadline day. After spending £42.5 million on Mesut Ozil a year ago and £35 million on Alexis Sanchez earlier this summer, manager Arsene Wenger put his chequebook away and stuck to his usual policy of financial stringency. That's despite the fact his club clearly needed a new striker before tonight's 11pm transfer cut-off point. With Oliver Giroud out injured until the New Year with a broken leg, the Gunners were in the market for a world-class centre-forward, but Wenger's hesitance (or even reluctance) to spend big means the Londoners are going to have to make do with misfit Lukas Podolski, rookies Joel Campbell, Yaya Sanogo and Chuba Akpom and Manchester United castoff Danny Welbeck. The club were linked with a number of big names this summer with a series of high profile, match winning strikers tipped with a move to Emirates Stadium only to end up elsewhere, while you could argue Wenger should have taken advantage of the window to rid himself of one or two misfits. No, it hasn't been the best of transfer windows for Arsenal, who paid over the odds on teenager Calum Chambers after handing Southampton £16 million for the youngster and lost Bacary Sagna to Manchester City. Things didn't get much better on the final day of the window, either, and here we take a look at Arsenal's 5 Biggest Deadline Day Errors.
