Does it even matter. He's five years older now and not the player he was 5 years ago. They'll add Coutinho (on loan), (probably) Mandzu and Cuisance (Gladbach). While Dortmund got better this window, IMO Bayern got worse (Ribeiry, Robben, Hummels). And this is only the Bundesliga competition. Their main opponnents internationally got better, too.
