Updated to include Otamendi, Stones, van Dijk and Christensen. I've also updated Martinez and Evans as I did them a few weeks ago and realised I'd used a couple of Inigo's Europa League stats rather than La Liga stats. Some perhaps surprising stats for the City lads but shows what Pep's looking for, so you can compare directly in categories where they are strongest as that relates best to what Pep's looking for:

The ranking obviously puts more weight on defensive work, so what's more interesting is where the other players relate to Ota and Stones in each category. From looking at it, I think Umtiti is in a class of his own out of our potential targets, breaking it down by our lads key strengths in our system:
Long Passing Accuracy (%): Christensen - 79.4 (11), Stones - 70.7 (10), Umtiti - 69.8 (9), Otamendi - 66.7 (8), Skriniar - 59.2 (7), Evans - 53.4 (6), Koulibaly - 50 (5).
Short Passing Accuracy (%): Stones - 98.2 (11), Christensen - 94.8 (10), Skriniar - 94.4 (9), Koulibaly - 94.1 (8), Umtiti - 94.1 (8), Otamendi - 94 (6), van Dijk - 92.4 (5).
Accurate Short Passes (P/G): Otamendi - 81 (11), Koulibaly - 73.3 (10), Umtiti - 67.1 (9), Stones - 65.3 (8), Skriniar - 50.9 (7), Christensen - 42.3 (6), van Dijk - 42.3 (6).
Aerial Success (%): Stones - 78.9 (11), van Dijk - 73.5 (10), Umtiti - 70.8 (9), Skriniar - 64.3 (8), Christensen - 60 (7), Maguire - 60 (7), Otamendi - 58.3 (5).
Dispossessed (P/G): Otamendi - 0 (11), Koulibaly - 0.1 (10), Christensen - 0.1 (10), Umtiti - 0.1 (10), Evans - 0.2 (7), van Dijk - 0.3 (6), Martinez - 0.4 (5), Stones - 0.4 (5).
Fouls Committed (P/G): Christensen - 0.3 (11), Stones - 0.4 (10), van Dijk - 0.5 (9), Otamendi - 0.7 (8), Maguire - 0.8 (7), Martinez - 0.8 (7),Umtiti - 0.9 (5).
Same names pop up most of the time. It's much more about our possession, range of passing, winning headers when needed and not giving away fouls rather than tackling people.
