Depends on the system. I think Rice’s ability to dictate play is underrated, but for arguments sake, let’s say it’s as mediocre as some in this thread are making out.
Arsenal have Raya as statistically the most aggressive keeper in terms of average position on the pitch. Saliba is a slick ball-playing CB. Gabriel can drive with the ball. Zinchenko and White are both very comfortable inverting. Odegaard is dropping deeper. Saka and Martinelli constantly make themselves available for an out ball. And Jesus plays as a false nine.
Rice doesn’t need to be 10/10 at dictating play in our system. All of our players are comfortable on the ball, so we’re not reliant upon one player with elite ball progression skills. The same was true of Casemiro at Madrid.
Of course, if you have Rodri, Modric, Scholes, Piri, Busquets (and Xavi and Iniesta, for that matter) you play to their strengths. But there is more than one way of being a top-class number 6.
