"He just seemed to be enjoying himself and was just another local boy, so easy going and one of the crowd.
"Even we were like little girls we were so excited to see him. It's great he came over and watched his sister play. She is also quite a talented player too and her team's doing really well this season."

"It's not like he puts himself on a pedestal, he was just one of the crowd."
