He's already missed Leipzig's pre-season, so there's not a tremendous benefit for him, for Leipzig or for RBNY if he goes over there now. If he went there now, it would be really hard for him to get any time on the field, although having Marsch there might help in that respect. Might as well wait until 1/1. Bundesliga has a long winter break where a lot of teams basically have another training camp. He can be there for that and be good to go for the second half of the Bundesliga season.
