World number two Andy Murray says he is "not sold" on plans to let cities bid to stage the Davis and Fed Cup finals.
A revamp of the team tennis events has been put forward by the International Tennis Federation (ITF).
Britain's Murray welcomed ITF proposals to shorten Davis Cup matches from best-of-five sets to best-of-three and stage finals over two days instead of three.
But he added: "The home and away aspect of the Davis Cup is something I enjoy and makes it different and special."
Other proposals include doubling the Fed Cup World Group to 16 teams to match the men's event.
