Tim Henman has criticised the current state of British men's tennis, describing it as "embarrassing".
"The signs are [Murray] will probably play against Croatia so I fancy their chances," Henman told BBC Sport.
"The fact we haven't got anyone else inside the top 200 in the world is still a bit embarrassing."
Britain set up the Croatia contest following a 3-2 victory over Russia in Coventry earlier this month.
Murray currently holds the rank of number two in the world, with Britain's next highest-rated player being James Ward in 217th.
