SCOTT McDonald says that playing as an attacking midfielder has opened his mind to new ideas.
McDonald has been a revelation in a deep-lying role this season but was previously opposed to the position and determined to be a central striker.
But the Australian has had a change of heart and now feels that Ian Holloway's tactical change has suited him well.
"I'm confident I can play anywhere, but I'm happy to play anywhere as well now," he said.
"That's important. You really have to happy in other positions, whereas maybe before I was thinking: 'I want to play up front, that's my position.'
"When you're younger you get caught in that mindset that it's your best position.
"That was the main reason why I came to Millwall – to play up front. That was my agreement with Steve Lomas when I signed, to play with a partner.
"But things happen in football when results don't come. Ideas and formations change. I'm adapting and I'm enjoying it – it's really opened my eyes and mind to all sorts of things.
"Playing in other positions teaches you about the game from different perspectives."
McDonald reckons he can have more influences over games from midfield.
He added: "That's the one thing people have seen and said. Even my wife said that I'm much more involved in the game.
"I'm really enjoying that part – getting on the ball and making things happen.
"When you play with a bigger guy up front, you are looked upon to drop deep a little and play in between the lines – so playing in this position isn't unfamiliar."
Despite feeling at home in midfield, McDonald would happily revert to playing up front.
"When you're playing one up front, especially now in this day and age, it's made for a bigger, physical guy.
"People don't necessarily look upon smaller-framed guys to play that position.
"But I believe I can do that, there's no question. Other people will look at it and say it isn't for me, but I've done it throughout my career.
"I've played in the Champions League as a lone striker."
