The Cronulla Sharks have offered fullback Valentine Holmes a mega five-year $4 million deal to remain at the club, according toย The Courier Mail.

The Sharks have reportedly lifted their efforts of retaining the 23-year old, who is contacted until 2020, but is eligible to to start negotiating with rival teams from November 1 this year.

The Cowboys have been linked to Holmes and are trying to bring the native North Queenslander make to his hometown, also reportedly offering him a full-time position as their starting fullback.

Sharks officials are pursuing a three-year extension to the high-flyer that would equate to a five-year package all up, worth at least $800,000 a season.

It is a contract that North Queensland may not be able to match, given lock Jason Taumalolo and Origin star Michael Morgan are on lucrative long-term deals.

Taumalolo believes Holmes would be an important addition to the Cowboys.

โ€œHe could (be great at the Cowboys). He definitely adds something to Cronulla,โ€ he told The Sunday Mail.

โ€œHe is one of those players that can turn nothing into something. That is what makes him so dangerous.

โ€œValโ€™s still at Cronulla, but if he does choose to come home he could definitely add something to the Cowboys.

โ€œHe could be that extra spark and X-factor. He can change games by himself.โ€

Queensland Origin selector Darren Lockyer said Holmes is an ideal prospect to build a club around.

โ€œHeโ€™s the type of guy you can build a club around for a long time,โ€ Lockyer toldย The Sunday Mail.

โ€œAt the start of the year, everyone was saying Val is only a winger but Iโ€™ve been really impressed with him as a fullback in the past month.

โ€œHe has developed a good passing game, he is reading the play well.

โ€œHe would be a great signing for the Cowboys but Iโ€™m sure Cronulla will do everything possible to keep him.โ€
