Sneyd was one of many high profile signings made by the Black and Whites for the 2015 season, having had a brilliant loan spell at Castleford Tigers under Daryl Powell the season before.
However the club had a disappointing season in Super League, finishing in 8th place and barely troubled the sides above them despite early season optimism.
Having seen Sneyd during last season and throughout pre-season, Watts believes that Sneyd has the qualities to push Hull FC further up the table this time around.
“Sneyd has come back to training playing well and looks really sharp,” Watts told the Hull Daily Mail.
“He’s kicking well and he’s been given a bit more ownership this year in the halves. He has taken on a more senior role and that’s what he needs to try and progress his game.”
With Hull FC bolstering the squad once more in the likes of Frank Pritchard and Scott Taylor, Watts believes that the 24 year-old playmaker is now the focal point that the squad needs to push for success in 2016.
“Sneydy’s getting a bit older now and he is not a young kid anymore,” he said.
“He will be our main leader this year to get us around the park. Everthing is going to be more or less coming off him.”
