Williams has it all on the pitch, technique, pace and power.
Off the pitch he seems caught between his obdurate Basque agent (his Barca move collapsed when they asked him to sack Félix Tainta) and his own caution about ever leaving his home turf.
If Williams were ever going to be the right signing for Arsenal, he'd already have left Athletic. His wage asks have not been calibrated, they've been the demands of a player who's already the main man at an elite club, the wages we should pay Saka or Saliba when they renew, if anyone. It's a no from me: on the evidence his mindset looks very far from what we need.
