Ferres, 26, returned to haunt former club Castleford on Saturday, scoring a try as the Giants came away from the Wish Communications Stadium with a 40-24 win.
The former Wakefield and Bradford man has been in inspired form at the start of 2013, as Huddersfield have cemented their place in the top few places of the Super League table.
Anderson told the club’s official website: “There are parts of his game that are great, and there are parts that can improve, so he’s only going to get better as time goes on.
“I thought he did well. It’s the reason I wanted to bring him in because he’s a good player and he can only get better.”
Ferres made seven appearances for Huddersfield last season, having joined mid-way through the year from Castleford.
He has made more than 175 appearances in Super League since making his debut for Bradford back in 2005.
