The game was tied at 1-1 following last weekend's first leg. But two goals from Ameobi put the Magpies on their way to complete a comfortable 3-0 win and earn a place in the UEFA Cup.
Roeder: "Shola should not have been out there. We kept it a secret. He picked up an ankle injury in training and he had no chance on Thursday.
"It just shows the character of the lad and the spirit in the team.
"I am delighted. While I didn't want to sound cocky or arrogant before the game, I was always confident of a display - and a result - like that. I could just see an improvement on the training ground as the week wore on.
"Some of our passing was sloppy last week. The movement wasn't there - but it was this afternoon. We got right at them from the off, and the two goals from Shola put us in a great position by half-time. They had to run at us and get the ball off us after that, and in that heat we made it tough for them.
"I was pleased to see Emre get his goal at the end - all in all it was a good afternoon for us."
