Toronto director of rugby Brian Noble says they will keep 90% of the players that have earned them promotion to Super League.
A 24-6 win over Featherstone in front of a record sell-out crowd at Lamport Stadium on Saturday meant the Wolfpack achieved their goal of reaching the top flight, after just three seasons in the game.
Noble said: “We’re keeping 90 per cent of this team because I think there’s 20 per cent improvement in them.
“We know we need to be a little bit faster and a little bit stronger but I think the character will get them through a lot of games next year.
“Clearly we need to add so there will be three or four players to come in.”
Toronto have been linked with big names from rugby union Sonny Bill Williams and Danny Cipriani in recent months.
Of the 17 that played in the Grand Final, only Andy Ackers and Blake Wallace don’t have top flight experience.
Australian quartet Chase Stanley, Ricky Leutele, Josh McCrone and Darcy Lussick would be new to Super League, having previously played in the NRL.
