Gran Canaria - Zenit Petersburg Basketball prediction

Gran Canaria historically is very strong at home. This season they have already beaten Real and Baskonia in convincing fashion. Most importantly they kept their core and are in much better form than most of the teams in Eurocup. 
Zenit has a decent roster, really. The problem is, they also have 10 new players. That's a completely new team + Karasev father and son. I think they are not ready to challenge any good team right now and they showed it a few days ago, losing to Unics away 60-94.
