Solanke is in one of the HG slots so only one that would potentially get his slot would be Davies. Someone else would have to come out for RKM
On balance I think I'd omit Tel from CL squad as he covers striker and LW - and we have 3 strikers now in RKM, Solanke and Richarlison now - whereas we only have one dribbly winger in Odobert. So we keep Oodbert in CL squad
With differing rules in PL squad, Tel is an u21 so we can keep him in PL squad
We may be playing 60 games this season (say 15 in CL, 45 in PL and domestic cups) but do not have a large CL squad so I'd keep Tel in the PL squad to rotate with other players. Its likely he will still have a lot of minutes to play ..... and we will avoid permanently tired/fatigued players that we saw a lot of last season.
