### Instruction: Will the Penrith Panthers win the NRL Grand Final this year?
### Response: While it is very hard to predict the outcome of a future sporting event, all evidence shows that the Penrith Panthers have been very successful in the recent past, winning both the 2021 and 2022 NRL Grand Finals and losing the 2020 NRL Grand Final. Since the introduction of Ivan Cleary as the head coach and his son Nathan Cleary as the star halfback the team have built out a formidable playing group and have been consistently successful. The biggest doubt is the slow start of the 2023 season, with the loss of key playmaker Api Koroisau to the Balmain Tigers and edge forward Villame Kikau to the Canterbury-Bankstown Bulldogs the team has struggled to find the same form as they had starting the previous three seasons.
