The controversy-ridden IPL outfit, which finished at the bottom of the table this year, also named Dav Whatmore as its new coach with Delhi Ranji coach Vijay Dahiya as his deputy.

Pakistani pace legend Wasim Akram was appointed the mentor of the side.

"Andrew Leipus and Adrian le Roux have been appointed physiotherapist and team trainer respectively," the team management said in a statement.

"The KKR management held several meetings over the past few weeks to discuss and plan the way forward for the franchise and the team. After weeks of careful deliberation, keeping in mind the vision and ideals of the team, the KKR management has appointed Dav Whatmore as the new team coach," the management said, adding Ganguly played an instrumental role in the entire process.

"KKR is looking forward to an exciting and successful season ahead with the new appointments and strategies in place. I am excited at the prospect of working with Dav and the entire team closely in addition to playing at our home ground once again," Ganguly said.

Insisting that Ganguly's position as captain is not merely ceremonial, the outfit said the former India skipper would be the "key driving force" who would "shape the cricket team" and "would be responsible for all cricket related decisions with regards to the 2010 season."

After leading the team in the inaugural IPL, Ganguly fell out with the then coach John Buchanan, who first mooted the "multi-captaincy" idea, which did not find favour with the management.

McCullum led the side in the second IPL but came a cropper. Hailing Whatmore's appointment, KKR co-owner Jay Mehta said, "Dav has the right vision not only for the team, but for each of the players, and for the franchise as a whole. He is very aware of our current position in IPL and knows that there is only one way to go now, up."
