He told the Fulham Chronicle: “I knuckled down to work on my fitness. I even went to America in January to really do some hard work in a clinic out there and I’m reaping the rewards now.
“It was called Athletes Performance Clinic. They work you hard. It was condensed training. There’s no rehab. It was what my body needed. They’re very advanced.
“It was the type of thing I had to do to get back playing in the Premier League. It’s one of the toughest leagues around.”
