The ongoing corona pandemic has created chaos in the tennis calendar and the same indoor arena in Cologne hosted two tournaments in a row.
Hamburg-born Zverev won the first final against Canadian Felix Auger-Aliassime on Sunday with 6-3.6-3.
Now tough papers await in the form of Schwartzman who went to the semifinals of the French Open where he lost to the final winner Rafael Nadal.
The tournament in Cologne is his first after Paris.
Zverev got revenge from the French Open
Zverev, who is ready for the Stockholm Open 2021 and 2022, won his semifinal against the Italian upstart Jannick Sinner with 7-6 (7-3), 6-3 and got revenge for the loss in the round of 16 in Paris, where Zverev controversially played with fever and runny nose without notifying the competition management.
He then tested negative for corona.
- I played against a player I lost to at Roland Garros.
It gnawed at the back of my head and I would not lose today, Zverev said after the match according to the ATP tour.
Schwartzman has hopes of disrupting Zverev.
- He is obsessed so far and maybe the final will be the first match he loses, the Argentine said.
