The club's owners, the Fsg, are looking to sell the club.
The company said it would consider new shareholders after it was reported that it had put the Merseysiders up for sale.
"We're exploring a sale, but there's no urgency, no time frame for us, and as far as I'm concerned, it's business as usual," Werner told the Boston Globe.
One outcome could be our stewardship for a long time.
The company was bought for $300 million in 2010.
John Henry is one of the principals of FSG and has been the company's chairman since 2001.
The basketball player has a 2% stake in the football team and has cost him almost $5 million.
He is now a partner in FSG, which is also the owner of the Boston Red Socks baseball team.
In March 2021, RedBird Capital Partners, a private investment firm, bought a stake in FSG for about $735m (£533m).
Sam Kennedy is a partner at FSG and he said that it is early days.
