Raina, who captains the IPL side Gujarat Lions, arrived here this afternoon, along with pacer Praveen Kumar.
"It was a collective effort, Indian team played as a unit and deserved to win the test series against Australia," Raina told reporters here.
A clinical India today regained the Border-Gavaskar Trophy, beating Australia by eight wickets in the deciding fourth Test in Dharamsala to clinch one of the most controversial and hard-fought bilateral contests in recent times.
Raina also praised his Gujarat Lions teammate and India player Ravindra Jadeja.
Meanwhile, franchise sources said that Head Coach Brad Hodge and bowling coach Heath Streak will join the team by March 31, while Jadeja and Brendon McCullum, are expected to reach the city by April 2.
