Newcastle 3-0 Portsmouth GIUSEPPE ROSSI made a splash on his full Newcastle debut to send Portsmouth sliding out.
The on-loan Manchester United forward notched his first goal for his new club just after the break to put Toon on the way to a last-16 clash at Watford.
And from then on the home side never looked back.
The win will relieve some of the pressure on Newcastle manager Glenn Roeder, whose side are showing some form as a cup team this season.
Goals: Rossi 48, Solano 53, 90.
Newcastle manager Glenn Roeder on Giuseppe Rossi:"He has been very patient waiting for an opportunity. He will certainly get plenty of opportunities between now and the end of December.
"It was a fantastic finish. I would expect him to finish there because I have seen it so often.
"I have seen it in games when he was at Manchester United, whether it was his opportunities in the first team or in reserve-team football.
"He is, in my opinion, a natural goalscorer, and he worked so hard for the team as well. He was a real pain for their defence."

Rossi scored the opener just after half-time.
