It was put in the pre-fight contract, guaranteed rematch clause.
Not sure if Wlad will take it, he would know himself if he has it left in him to substantially up his game for a rematch or if his decline is irreversible.
To lose in this fashion for a second time will really tear into his reputation and legacy within boxing (As padded as that legacy is!)
What surprised me in the fight was that he looked physically drained in the latter rounds while Fury was still quite fresh.
I doubt he took this camp lightly so only other explanation is that he just physically can't cope with the demands any more, hasn't been able to for a while but poor opponents masked it for him.
I don't see a second loss to Fury tarnishing Wlad's record hugely in the long term. Once a boxer hits his late 30's, he's pretty much living on borrowed time. It's quite alarming how quickly some athletes can deteriorate once they reach a certain age and I think most boxing fans will understand this.
The best situation for Wlad would be to avenge the loss (prefably with a stoppage) and retire as the champ.
Credit to Fury for winning but with all due respect to him, it just looks odd seeing someone of his ability as the HW champion.
Wlad really though should have quit after he beat Povetkin. There wasn't anyone else left for him to beat at that point and it would have opened the division up. The wins he's had since then have been somewhat irrelevant (although his destruction of Pulev was good).
