So thought I'd post this one, I had a look at centre back pairings. Stats are from whoscored, only centre back league starts are included, some games were tougher than others, too few games to draw conclusions on some partnerships, goals scored is not that relevant etc. Holgate played right back in some games and I've probably cocked something up.
Things of interest:-
5 out of 7 of our wins have come from Holgate/Williams at centre back, with 2 draws and no losses, conceding only 4. We've conceded 35 goals and taken only 11 points from the other 17 games.
Jagielka and Williams have only played together once, given that Holgate had not featured much as centre back until this season, that's not a lot of familiarity or experience of playing together. It's largely 2 distinct new partnerships, Jagielka and Holgate have played together once, and surprised by Jags poor ratings.
We played Holgate and Williams together for 5 matches in a row, won 4, drew 1, including our last win. Allardyce rotated for the next 5 games and only switched back last match.
