An 18-year-old centre who in September was re-signed through to the 2021 season, Xerri is a Sharks junior from Endeavour Sports High School who scored a hat-trick on his Intrust Super Premiership debut with the Newtown Jets in 2018.
He's been selected in the Australian Schoolboys side to tour the UK as well as the NSW under 18s and under 20s sides, and helped the Sharks to this year's Jersey Flegg title, scoring a try in the grand final.
Valentine Holmes' decision to chase an NFL dream opens up a position somewhere in the Sharks backline, depending on how the club opts to replace him.
If NSW Blues No.1 Josh Dugan is moved to fullback – either at the start of the season or at some point during the year – that would open up a position in the centres where Xerri could make his mark.
Having lost Jesse Ramien to the Knights, Cronulla could do with another young strikecentre and Xerri, although young, could fit the bill.
At 18, Xerri is very young and remains a risky selection for a Sharks side that is still a chance of challenging for the premiership.
More experienced campaigners Sosaia Feki and Aaron Gray could be ahead of him in the pecking order, while there's still every chance Dugan remains in the centres along with fellow veteran Josh Morris with Matt Moylan replacing Holmes at fullback.
If Xerri is left out of the Sharks' round one outfit and you pick him in your Fantasy squad anyway, there's a very real chance you'll be stuck with a non-playing reserve all season.
To buy or not to buy?
If he's picked in round one he'll rocket up the cash cow rankings but at this point Xerri is a gamble, and with the presence of Dugan, Morris, Shaun Johnson and Moylan in the Cronulla squad – plus the talented Kyle Flanagan – Xerri's job security will always be a question mark.
