Great Britain's players are "bouncing" going into the Davis Cup quarter-final against Germany in Innsbruck on Tuesday, says captain Leon Smith.
Britain are in the last eight for the sixth time since 2014 and Smith says team spirit is vital to their success.
They are aiming to triumph for a second time under Smith after success in 2015.
"We spend a lot of time together because we enjoy each other's company. It's been like that for a long time and long may it continue," said the Scot.
Britain reached the last eight at this year's Davis Cup Finals - which featured 18 nations playing their group ties in Innsbruck, Turin or Madrid - after beating France and the Czech Republic in the round-robin stage.
