he can also gain back time in the ITT. Sure, Pogacar finished only 24s behind Ganna in UAE - but Engels said that the aim is to win that one, so they seem to be confident that van Aert is better than Ganna now
If they are that confident in his ITT then I would think one more stage win with the bonus seconds will likely be enough to podium the final GC behind Pogacar and Bernal.
That would be a sensational result.
