That lad from Leverkusen sounds like he will available on a loan to buy deal and I think that would be a good move for us.
All the other positions are in that grey area for Saints. Where you want to strengthen the squad, but you want to keep that much praised pathway.
McCarthy, Targett, Isgrove, McQueen & Gallagher are all potentially a suspension/injury away from starting. Some fans may think that's exciting and others will be filled with dread. I believe Koeman will use the Millwall match to assess some of those players in a competitive match and that will go towards dictating how active we are at the end of the window.
