(Reuters) - Everton boss Rafa Benitez said he had overcome the nerves that he would experience in the Goodison Park dugout as an opposition manager following Saturday's 3-1 victory over Southampton in their Premier League opener. Benitez said the positive mood in the stadium was down to the efforts of his players. After so many months, the players really appreciated the support and the fans appreciated the commitment of the players," Benitez told reporters, before vowing to win over his critics. I was nervous when I came as an opposition manager but not today. Benitez said he was pleased with Richarlison, who returned after helping Brazil win gold at the Tokyo Olympics.
