Rice can play 6 very well in most situations. I wouldn't love him doing that away in Europe maybe, but he is still excellent there. The pendulum has swung too far to the "Rice is an 8" direction, exacerbated a bit by his struggles to successfully be a one-man midfield in a disjointed England setup.
mdgoonah41 Arteta isn't obsessed with buying defensive players. People forget that we were all in on Sesko, and would have signed him if he hadn't elected to stay another year in Leipzig. He is particular about buying players for his style of football, which is exactly what you want in a manager. And unfortunately you can't write a check and make a "true DM" appear. If Zubimendi were available, you can guarantee we'd be desperate to get him, and have the funds to do so. You want to spend £100m on a tiny 19-year-old DM in Neves, like PSG? I'm glad we've stayed away.
