Akanji isn't going to offer a realistic option outside, like Nunes, and he isn't going to come inside and, like you say, move it forward, like Lewis. It's not his skillset and that cross into the stand just showcased it. But if he gets it in the right back position it is inevitably always going to go square to Savinho, then back, or sideways to Dias or a dropping midfielder. Against 11 defenders, it didn't work out.
Clearly he played as Pep thought one fullback roaming was enough, and Akanji has the pace to deal with Eze. But when it became very apparent that palace were not being very adventurous, and our creativity was a problem, then it should have changed. My preference would have been Nunes as he will go to he byline and he will get a cross to Haaland. Yes he'd be exposed on the break and it may have ended up two nil, but it's a cup final and we needed a goal.
The opposition know that if Akanji or Dias gets the ball, then it certainly isn't going to be a progressive pass and it will be moved sideways. Far too often the ball was to where Savinho is, not where he wanted to be, who had to cut back inside. It's not Akanji's fault that he can't see a through ball or move it quickly, it's not his game, but I think we could have taken more of a chance by bringing either him or Dias off for a more forward thinking player with at least ten to go.
