The Suns have been shopping star midfielder Liam Williams for the past week, according to reports.

The Suns have reportedly made $6 million in the deal and have already made two big moves in the trade market.

The 20-year-old was a key part of the Suns’ successful 2015-16 campaign and his deal comes on the heels of the club’s acquisition of former Blues star Josh Kennedy.

Williams, who made his debut in the AFL season in 2016, had been a target for several clubs in the past month.

But, according for the Suns, he will be signed by the club for an undisclosed fee on Sunday.

A source told the Herald Sun the Suns had “made a huge decision” to bring Williams in and are confident in their negotiating position.

“It’s a huge investment for us,” the source said.

“The signing of Liam means we’re in a much better position now than we were in the summer, but we’re still waiting for a contract to be signed and Liam will be a part of our team for the foreseeable future.”

Williams, the top-ranked player in the A-League, played a pivotal role in the Suns winning the 2017 Grand Final.

The versatile midfielder has scored 17 goals in 26 games this season and will be competing with the likes of Luke Hodge and Josh Kennedy for a place in the starting side for the 2019-20 season.

Williams was also a key member of the Blues team that won the NRL title in 2015, while he was a regular in the Blues’ Origin side.

He joined Merced from Melbourne City in the 2016 season and had played under former Blues coach and current Newcastle coach Shane Richardson.

“I’m really happy about it,” Williams said.

“I was really excited to come and play in the competition, I felt like it was a great fit for me, I’m very excited about it.”

A lot of people have asked me, ‘what do you want to do?’.

It was just about finding the right club for me.

“We’ve had a really good conversation with the Suns about the offer, the market, what we need, we’re really confident in what we’re getting.”

When I came to Merced I didn’t know any better than anyone else what the market was like and I just wanted to do my best for the club and the club was just really great.

“Hopefully it’s going to pay off for me.”
