The Brazilian is back in contention for the Boxing Day trip to Hull, following a three-game ban for a red card against Chelsea.
The Blues manager admitted his midfielder had been missed.
“It is so important he is back. We are happy.
“At Leicester, sure [we missed him].”
When asked how he felt about Boxing Day games – in particular his first – Guardiola added: “I watched them on TV or live when I came for holidays to London.
“I enjoyed them a lot. They are beautiful.”
“I cannot sleep!” he joked.
