Arsenal's transfer work in the past 18 months has been largely flawless. Both in terms of incomings and outgoings there has been little to point to, even in hindsight, and say it was misjudged.
Last year there were question marks over Aaron Ramsdale, Ben White and the decision to continue giving Granit Xhaka opportunities. Kieran Tierney hadn't kicked on with his injury issues and Takehiro Tomiyasu was an unknown quantity. Over the course of the year there was uncertainty over what sort of risk Martin Odegaard would be.
Now there's little doubt. Arsenal have reaped the rewards of each of these signings and their choices to be loyal to their players. The summer business fitted the planning and far from just adding experience of winning with Oleksandr Zinchenko and Gabriel Jesus, they fitted the wider mould.
