Manchester City have announced the signing of Brazilian Fernandinho from Shakhtar Donetsk in a deal believed to be worth around £30 million.
The 28-year-old, who impressed in the Champions League this season, will wear the number 25 shirt.
"This is a change, a challenge and a chance that I have been waiting a long time for. Playing in the Premier League for City is like a dream," he told Manchester City's official website.
“My ambition here is to win all the titles, the team here is strong, and so is the greatness of the club and the supporters. Professionally this is a spectacular thing. Playing for a huge club in a huge league makes me so happy. I hope I will be able to repay City for what they have done for me.
“I know I will face challenges but I am prepared for them. Every player at a high level faces pressure and must respond and I am ready for that too. I know a lot about City. Ever since they expressed an interest in me, I have been learning more.
Fernandinho, who has also had a spell at Atlético Paranaense, has put pen to paper on a four-year contract at the Etihad Stadium.
His arrival is expected to be followed by that of Sevilla winger Jesus Navas, who should complete his move in the coming days.
