He's willing to accept a trade to the Anaheim Ducks, Los Angeles Kings and New York Rangers, and it's believed he would consider other options, such as the Chicago Blackhawks and Nashville Predators.
While a trade to the Ducks or Kings is highly unlikely, and the Rangers unlikely due to salary cap restrictions, if Marleau's dealt, it's expected to be a different team, possibly Chicago or Nashville, or another club, such as the Ottawa Senators, who have expressed interest in the past.
Outside of Marleau's situation, Sharks GM Doug Wilson is expected to be a buyer in the next 19 days, reports the San Jose Mercury News.
According to the Mercury News, the Sharks could look to add depth on their blueline or on the wing.
One player the Sharks have reportedly shown some interest in is Toronto Maple Leafs defenseman Roman Polak, who is in the final year of his contract and is expected to be dealt by the deadline.
The Sharks have roughly $5.6 million in available cap space, according to generalfanager.com.
