McArthur proud of progress at Wigan
The midfielder has become a first-choice in Roberto Martinez's midfield.
"I'm a better player, there's no doubt about that," he told the Scottish Sun.
"Everyone is the same. The more you play the better you become.
"The manager and Wigan have helped take me on to another level from the one that I was on at Hamilton.
"I'm learning things every day and with every game I play. That can only benefit me and the team."
