Sevilla midfielder Ivan Rakitic says there's more to come from him.

The summer signing from Barcelona has admitted he needs time to readjust to life in the Andalusian city.

"I'm going to be judged by what I do on the pitch," he said.

"It's normal that I need a little time to adjust; Barcelona isn't the same as Sevilla.

"They play differently, we are very competitive, but I understand I have to build rhythm and understand my teammates. Every day that goes by we are improving and the last two weeks have been very important for me."
