The attacker spent part of last term on-loan at Cardiff City.
“This is an important season but they are all important,” he told the Evening Chronicle.
“I am frustrated so far because I have not really had a chance without injuries getting in the way. Newcastle supporters haven’t seen enough of me with the injuries so that is now the main thing for me – just to stay fit for long enough to have a chance.
“It is great for me to have these games in pre-season because I know it is up to me and I feel happy and I feel strong.
“The manager has said that he’s happy with me. He thinks I will get a chance because players might be tired in the Premier League with all the added games.”
