The final six teams confirmed their spots in the last eight of the Davis Cup after Kazakhstan and the United States secured their places yesterday.

Germany had a 2-1 lead going into today’s match against Australia and secured their place in the quarter-final thanks to world number five Alexander Zverev’s straight-sets victory over 2016 Hopman Cup winner Nick Kyrgios - 6-2, 7-6, 6-2 - away on the hard court at the Pat Rafter Arena in Brisbane.

They are now due to face Spain, who also needed just one match win in their tie against Great Britain and book their place in the last eight.

They recorded that win thanks to Albert Ramos Viñolas' 7-6, 2-6, 7-6, 6-2 win against tournament debutant Cameron Norrie on the clay at Marbella’s Club de Tenis Puente Romano.

Italy secured a 3-1 victory against Japan thanks to 2015 Australian Open champion Fabio Fognini, who completed an excellent comeback on the hard court at the Morioka Takaya Arena in Morioka to win 3-6, 6-1, 3-6, 7-6, 7-5 against 2016 Olympian Yūichi Sugita.

They are now scheduled to face defending champions France after Adrian Mannarino secured a 3-1 victory for his side by beating Robin Haase of The Netherlands 4-6, 7-6, 7-5, 6-7, 7-5 in a gruelling five-setter on the hard court at Halle Olympique in Albertville - a match which took more than four hours to complete.
