When Aston Villa tried to sign Emile Smith Rowe two years ago, Arsenal laughed off the £25 million ($30m) bid - and it was easy to understand why. The Gunners had absolutely no intention of selling one of the most exciting players to come out of their academy in years - and certainly not for such a derisory fee.
The club had big plans for the versatile attacking midfielder, as they almost immediately underlined by giving him a new contract - and the No.10 jersey that had been vacated by Mesut Ozil earlier in the year.
It may have been just a shirt change but it felt like a very symbolic moment, a clear signal of a shift in the club's player recruitment policy, moving away from the costly obsession with star names that had marred the final years of Ivan Gazidis' tenure as chief executive towards a more sensible approach to squad-building that focused on young talent.
