“We have a lot of injuries at the moment and I had to take a gamble on Anderson's fitness,” he explained. “He's been training very well for 10 days but it was his first game back and it wasn't easy for him. But he didn't let us down. He did his best.”

“We know we can improve on today's performance,” he said. “We won't get many like that. I'm confident we'll give it [the title] a real go.”
