Marazzina hopes to deliver next term
The striker is on-loan from Chievo but has seen his chances limited due to the return to form of super brat Antonio Cassano.
"I'm not playing much now but Cassano deserves a regular place in the team," said Marazzina.
"The chance to show my capabilities are not very frequent and I am running out of games.
"I'll have to use each minute at my disposal and make them count.
"I know Roma are on the look-out for a forward. I just have to continue in my own way.
"It's not my job to think about these things."
As for the Roman side's interest in his Flying Donkeys team-mate Nicola Legottaglie, Marazzina said: "He's great, as a man and as a player."
