The former Canaries man believes Rafael Benitez's side have a very tough task in store at Carrow Road.
Rafael Benitez's Magpies side go into the pivotal clash second bottom of the Premier League table, three points adrift of Alex Neil's men and safety with just eight matches remaining.
Defeat in Saturday's meeting would leave a six-point gap between the North East club and 17th spot, and although Newcastle would still have a game in hand over Norwich, the psychological effect could be hugely damaging to their survival bid.
Dublin, who scored 16 goals in 79 appearances for the Canaries at the end of his career, revealed in his prediction for Predikta that he thinks Alex Neil will set his side up in a manner which will make it too difficult for Newcastle to find the net.
The 46-year-old said: "I can't see Newcastle getting anything from this game, Alex Neil is going to set them [Norwich] up not to concede at all and I think Newcastle are going to have a very physical game [on their hands].
"So I fancy Norwich and a lot of goals - 3-2."
It is no surprise that Dublin doesn't fancy Newcastle to win away from home - the Magpies have lost their last seven league matches on their travels in a row, scoring just two goals in that time.
Meanwhile, the hosts may have returned to form at just the right time, beating West Bromwich Albion 1-0 at the Hawthorns in the last match before the international break to record their first victory since 2 January.
