The Swede earned and converted a penalty in Friday's 2-0 victory away to Genoa.
"We scored in the second half, but created plenty of chances throughout the game and if we continue like this then it'll be hard to stop us," said Ibra.
"We're giving great responses away from home, where we impose our football on the game and score regularly.
"My position? I like to be free on the pitch. The Coach gives me this possibility and for the moment it works."
