There were rumours that Guardiola had spoken personally with Everton to discuss a potential move to the Etihad and the Brazil international was quizzed on the recent speculation.
Asked about his apparent phone call with Guardiola, Everton replied: Its a dream, right? Every player dreams of playing at high level, playing in Europe, reaching the national team.
And with me its no different.
I think that when you are in a good sequence like this, at a stage like I am living, you are observed, monitored by several clubs
My phone hasnt rung yet, but who knows if hell call.
When a reporter jokingly asked if he wanted Guardiolas number, Everton responded: I do, if you have it, I want it!
Everton poured cold water on speculation that he could be set for a move to Old Trafford earlier this week.
We all hear the rumours at some point, right? he told SporTV.
Im going through an exceptional phase, and we know how hard it is when clubs from England look at Brazilian players, for their quality.
