If part of the "grand plan" for Klopp involves bringing in Andre for £25m in January, then this window has been a 6.5. And it will become an 8, looking back, in January.
If we have no plans to buy a DM in January, then I have to say it's been a 6 (depending on how fit our CBs stay).
If they stay fit, it's a 6.
If they do not, and we're shuffling people around, it's a 3.
