OG's new offlaner will likely be Wisper's replacement, Abdimalik "Malik" Sailau, according to information from Alexey "STORM" Tumanov.
This news was posted on Dota 2 Media's Telegram channel:
“Malik would be the perfect addition to replace Wisper in the OG squad, if Wisper moves to the Heroic squad, which makes perfect sense since Davai Lama has left Heroic.”
Based on rumors that there has been no official announcement from the club about why Wisper left OG, STORM believes that it is likely that Wisper will move to Heroic, and Malik will join OG after leaving Team Spirit. This is a completely possible possibility.
Dmitry "Korb3n" Belov, Team Spirit's manager, also hinted that Malik seems to have found a new team for himself.
Additionally, the announcement from Vladimir "Maelstorm" Kuzminov about Team Spirit's new roster, which includes Ilya "Yatoro" Mularchuk and does not include Denis "Larl" Sigitov, further solidifies the possibility of a roster change.
