Beware The Ali Monster !

Warriors coach Daniel Anderson issued a warning on Tuesday to his National Rugby League club's finals rivals: Beware Ali Lauiti'iti.

Lauiti'iti, the reigning Dally M second rower of the year, has struggled to make a significant impact since returning from serious arm surgery in July.

Lauiti'iti's statistics are down across the board, in part due to Anderson using the classy forward off the bench.

But, even allowing for that, there's no hiding Lauiti'iti has struggled to match last seasons achievements , when he was rated the most damaging forward in the game.

"The main difference is Sione Faumuina is in his position so he's not playing on the edge where there's a little bit more space," Anderson said.

"He's now playing in the middle where he's getting three and four blokes on him.

"I think he's doing the hard yards perfect for us.

"I don't think there's anything too dramatic.

"Beware of Ali's talent in the good end of the field, he's still got everything he's always had."

Lauiti'iti missed the start of this season when tests diagnosed a cyst which had eaten away the bone in the upper part of his right arm.

A bone graft had Lauiti'iti back on the field ahead of schedule, but since his return he's struggled to find his previous form.

"He hasn't had much possession in the good end of the field," Anderson said.

"When he does he still has the same attacking talent that he's (always had)."

Penrith coach John Lang took heed of Anderson's warning, describing Lauiti'iti as a dangerous man.

"Ali's a very big man," Lang said.

"He's got really everything.

"He's got speed, footwork, speed, ability to offload a ball."
