Robert Lewandowski ended his eight-year spell with Bayern Munich.
The 33-year-old striker joined Barcelona on a four-year deal which is believed to be worth around €45million.
He has undergone a medical in Miami and will be announced as early as this week.
“Yes finally I’m here, I’m very happy,” the Poland striker said. “I’m very happy to come and join Barcelona and to be here.
“A new challenge but always I am the guy who wants to win not only the game but also the titles.
“At Barca it’s time to get back on track so I am here to help Barcelona to be on the top. And to win as many titles as possible.”
He then revealed that Xavi played a huge role in his move to the Camp Nou.
