Bernard Dunne's manager believes the fighter is entering the danger zone when he makes the mandatory defence of his European super-bantamweight title.
Dunne was a unanimous points winner over Norway's Reidar Walstad in Dublin on Saturday, leaving the challenger's face a mess after 12 rounds.
Now the 27-year-old must look ahead to a mandatory defence against unbeaten Spaniard Kiko Martinez. manager Brian Peters said: "Martinez is a very dangerous fighter. This is a fight that will be a defining part of Bernard's career."
