It's been a little quieter on the transfer front for Arsenal recently, but that's not to say things aren't happening behind the scenes. Following the win over FC Nurnberg last week, Mikel Arteta confirmed that there were still things the club would like to do, but reiterated that the market would 'dictate' what's possible.
Perhaps that was a slight hint towards the Lisandro Martinez situation. Arsenal had been in serious talks with Ajax regarding the Argentinian and even saw bids rejected, but eventually, Manchester United came in and matched the increasing financial demands that were being set.
For a lot of clubs including Arsenal, a fair amount of business has been done already, especially in terms of incomings. Four new faces have arrived, three of which are very attacking-minded. However, it highlights the need for reinforcements in other areas of the squad and it's something that Arteta and technical director Edu are aware of.
