Great Britain's Davis Cup captain Leon Smith says his squad "lack depth" but remained positive about their progress despite defeat in the quarter-finals.
Britain - without world number one Andy Murray - were knocked out by France on Saturday, going down 3-0 in Rouen.
It was their first defeat over two days since 2009 - the year before Leon Smith took over the captaincy.
"A quarter-final, a win, a semi-final, a quarter-final - in decades previous you weren't getting that," said Smith.
"It's a damn sight better than it used to be but there's still work to be done.
