As good as he is surely you've got to start building around Fofana and Badiashile now? Bit bemused to see Fofana as unused sub today unless he's still struggling with injury.
Think Poch played 3atb on some periods at Spurs but their best spells were with a back 4 and Silva isn't quite as dominated in that system compared to 3 man defence.
Like most positions at Chelsea there's just so many question marks and in reality it's going to take three transfer windows to sort out.
Oh it's of course fecking ridiculous that Lampard was playing Silva, Kante, Sterling, and the corpse of Azpilicueta on a regular basis until today. I do think though that Fofana is just coming back from a minor injury? So not the end of the world there - but the reluctance to play what may ostensibly be the first choice partnership next year is totally idiotic as you say.
Spurs under Poch played a more or less hybrid system between 3 and 4 at the back - Dier started in midfield and would drop between Vertonghen and Alderweireld as they moved wide to cover the gaps left by the aggressive fullbacks. I could be crazy but this feels like a potential fit for Reece James given his previous experience in midfield, his injury issues when left to run up and down a whole flank, and his composure and physicality on the ball?
That said, the last player I'm worried about is Thiago Silva - I think the lack of team success when we've played 4ATB has obscured how good he still remains in that type of system overall. Perhaps not as dominating (and not as able to dictate possession from deep), but I'd argue equally impressive overall.
