Roger Federer and Rafael Nadal insist they will always be rivals

Roger Federer and Rafael Nadal took Team Europe to within two wins of lifting the Laver Cup as they won their singles and their first-ever doubles rubber together in Prague on Saturday. The world's highest ranking duo handed Team Europe skippered by Bjorn Borg a 9-3 lead over Team World captained by John McEnroe after two days. After Nadal and Federer had won their singles rubbers, all eyes at Prague's sold-out O2 Arena were then on the two legends who played on the same side of the net for the first time in careers which have stretched the best part of two decades. Despite their dominance together, the two insist they will forever remain rivals.
