Gary Anderson insists he managed to retain his PDC World Darts Championship title by playing only "85% of my best game."

The Scot beat Adrian Lewis 7-5 at the Alexandra Palace on Sunday to back up the maiden title he won against Phil Taylor a year ago. For those watching this was another epic contest, Anderson and Lewis nailing 34 180s for a darts record in a single match.

"The way I've played in the tournament, I think I've deserved this," Anderson told the PDC website. "It never really clicked but there was some great darts.

"It's great to have defended the title. It feels fantastic and I probably did it at 85 per cent of my best game."

Anderson, 45, appeared to be at 100 per cent when he checked out on 170 in the final set, but added: "I've got the trophy for another 12 months at least.

"It would be lovely to make it a hat-trick next year and do something really special but I'm not getting any younger.

"I'll keep plodding on and see what happens."
