Great Britain's Davis Cup captain Leon Smith defended his team selection after the hosts failed to qualify for the knockout stage of the competition.
There had been wide agreement before this week's group stage in Glasgow that the 10-time champions had their strongest ever team in terms of depth.
Cameron Norrie, Dan Evans and Andy Murray are top-50 ranked in singles and Joe Salisbury and Neal Skupski are the top and third-ranked doubles players.
Murray played doubles ahead of Skupski.
"Is it that controversial to put your two highest ranked singles players out there? No," Smith told BBC Sport.
