Guardiola has revealed his former assistant's “struggles" since taking over at the Emirates before Christmas, but insists Arteta has been outstanding in just a matter of weeks in the role.
“It was an incredible relationship," he said. “We are in touch quite often by phone.
“He's so excited, so happy, struggling because it is always not easy to take a team in the beginning. But he is doing incredibly well, off and on the pitch. He decided to move. For people I love, I always want the best and he decided that. I wish him all the best. He knows that."
