Both McGovern and Andrew Gaff are free agents for the Eagles this summer, and are already pulling at the West Coast club's purse strings.

Fairfax are reporting the Eagles have offered McGovern a long-term contract worth $4 million over five years.

The two-time All Australian led the AFL in intercepted marks lasts season, and Lyon reckons they're getting their money's worth.

“He’s an influential player,” Lyon said on SEN Breakfast.

“When you’re going to spend that sort of money, you want someone that influences results and I think he’s able to do that.

“He’s a marking machine in the back half and he can go forward and kick goals.

“It gets back to this multidimensional player that you need to be, if you’re going to earn that sort of money.”
