Patrick Roberts admitted he had to persuade Manchester City chiefs to allow him to return to to Celtic.
The winger was desperate to sign on again at Parkhead after playing a vital part for Brendan Rodgers' 'Invincibles' last term as they completed a remarkable undefeated domestic campaign.
He has now sealed a one-year loan with the Scottish champions, but only after convincing City boss Pep Guardiola that Glasgow was the best place for him to develop his skills.
The Spaniard was reluctant to allow his talented 20-year-old - who had been linked with moves to Premier League big guns Southampton and French side Nice - to spend another 12 months north of the border.
But Roberts dug his heels in and got the move he wanted.
"I had to express how much I wanted to come here for myself to improve as a player," said Roberts at his official unveiling. "I enjoyed the last 12 months and the six months before that so it was my decision to come back here.
"I thought this is the best place for me to develop."
