I think we've got the squad to compete for everything this season and playing the odd first teamer might be necessary in the areas we don't have depth.
We do in other areas but not in defence.
We all knew this was going to be an issue given how injury prone both Matip and Gomez have been in the past.
Every game is a risk but at least if a key player gets injured in a PL / CL game, we'd say it was unavoidable.
If we lost a key player to a challenge by an exuberant youngster / squaddie keen to impress in the League Cup, what would we say?
That it was a risk worth taking?
It's just not.
We didn't buy to compete on all fronts so we shouldn't try.
