Rotating centrebacks is moronic, especially when Dias and Stones merged so well last season, won us the league were possibly the biggest factor in us going further in the Champions League than ever before; both have suffered this year because of it. Laporte seems to have a parasitical impact on both of them when partnered with him for some reason, potentially his personality.
I’d try to restore the Stones-Dias partnership in the new year as the Champions League games will expose Dias’ flaws without his pal, while Laporte himself has previous as a big game bottle job.
