He said the administrators of the game will have to find out innovative ways to make Test cricket more viewer-friendly and exciting.
"Twenty20 is a form of entertainment, you go there to enjoy yourself. I feel the BCCI will have to take initiatives to make Test cricket more interesting," Raina said at 'Agenda', a conclave organised by a private Hindi news channel here.
Asked about the pressure on Sachin Tendulkar to quit the game in the wake of former Australia captain Ricky Ponting's retirement earlier this week, Raina said the decision should left to the champion batsman.
"He (Sachin) is a great source of inspiration for us in the dressing room. His presence gives us energy. Soon, he will be the only player to play 200 Tests in the history of the game. The decision to retire or not is totally upto him," the left-handed batsman said.
