In 2008, his Russian club Ak Bars Kazan joined the Kontinetal Hockey League.
Although Morozov was limited to only 49 games due to a freak head-on collision with Atlant Moscow goaltender Ray Emery, he finished second in scoring with 70 points (32 goals and 38 assists).
Following the season's end, Ak Bars swept Barys Astana in the Round of 16 and defeat them in season series 3–0.
In the quarterfinals they would face the talent-laden Avangard Omsk and dispatch them in a final decisive game five 3–2 in overtime.

For the semifinals and finals matches, the playoff series length was increased to seven games for the final four teams in it and in their semifinal match-up, Kazan defeated Dynamo Moscow 4–2 and would go on to face Lokomotiv Yaroslavl in the finals, making it the third time in five years that Ak Bars has made it to the finals.
Although Ak Bars would get off to a slow start, getting outscored in their first three games by a combined score of 9–4, including two shutout losses, they and captain Aleksey Morozov would turn it on when it mattered.
Finding themselves down 3–2 in the series, Ak Bars would snatch game six away from Lokomotiv in overtime and in the final decisive game seven their captain provided all the offense the team needed as Morozov scored the lone goal in a 1–0 victory, making Kazan the first team to ever capture the Gagarin Cup and first-ever KHL champions.

Due to his incredible success in the KHL as well as his previous success in captaining Russia to a World Championship, Morozov was once again chosen as captain for the 2009 IHWC squad.
He would not disappoint, as Russia would go on to steamroll their opponents in the opening rounds of play and would soon find themselves in a rematch of the previous year's championship game against Canada.
In yet another exciting contest, Russia would once again capture the Gold by defeating Canada 2–1 giving them the most Gold Medals by any country with 25.
From 2006 to 2009, Team Russia was a perfect 21–0 with Morozov in their lineup in World Championship hockey.
