Championship stats only:
Harry needs 1 more goal. He has 13 assists
Kebano needs 1 more goal and 4 more assists
Mitro needs 3 more assists
Carvalho needs 3 more goals and 5 more assists
De Cordova-Reid needs 4 more goals and 4 more assists
Since BDR mainly starts on the bench I'd say he's least likely to reach the double milestone but that's potentially 5 players from the same team that could achieve a double double in the same season.
Has to be close to, if not, a record of some sort 🤷🏻♂️
