Tarkowski and Branthwaite have been the first choice centre back pairing now for some time under both Dyche and Moyes.Dyche would want to start him.
Moyes won't
Not bothered either way but Moyes wanting Keane is as predictable as night following day.
If either of these was injured last season then it was a choice between Keane and O Brien as replacement.
We know that O Brien sorted out the problem right back situation so Moyes was slow to move him into the middle and Dyche for some reason ignored O Brien.... for these reasons Keane got a few games and tbf he generally did well.
