"Cooky was the one who told me I was making my Test debut so that always holds a great place in my heart," said Finn. "That was the first experience I had of being in an England dressing room and Alastair was excellent at welcoming me in and making me feel like one of the boys.
"Cooky is a similar sort of leader to Straussy. He leads from the front as an opening batsman and setting the tone is very good for a captain.
"I think the transition between the two will be smooth in that Alastair has been used to working with Andy Flower as a one-day captain."
England, who face South Africa in the third one-day international at The Oval on Friday, currently trail the series 1-0.
