Jamie Carragher once saw fit to take aim at Arsenal's transfer business, labelling three previous recruits as "a joke".
The Gunners are now mounting a title challenge just over two years after Carragher's comments lamenting their recruitment. Since then the north Londoners have changed their approach in the market, targeting younger players, and they have very much benefitted from a change in emphasis.
It highlights how far they've come having endured difficult periods early in Mikel Arteta's reign. In the Spaniard's first summer they went after established stars, several of whom were deemed surplus to requirements at their current clubs and allowed to join the Gunners.
