Sea Eagles co-captain Jason King has challenged his team mates to improve on their bruising win against the Roosters when they take on the Wests Tigers this Sunday.

King missed the Grand Final re-match through suspension and while impressed with Manly's ability to overcome the absence of several stars to take the two points he warned there is plenty of room for improvement.

"It was really pleasing. I thought we played some tough, really grinding football but we did identify some areas that we really need to improve" said King.

King also believes the week off was a blessing in disguise as he re-adapts to the rigours of NRL football again after almost 12 months on the sidelines.

"I've had a little bit more time to work on my fitness and some areas of my game and I'll be ready to go this Sunday" he said.

The Sea Eagles will be chasing a fourth straight victory when they travel to Leichhardt Oval to meet the Tigers and King is wary.

"There'll be looking to bounce back after a loss like all teams are and we're going to have to play very well to beat them."
