“Barca is back where it belongs,” he added. “I will never forget the love I received from the fans from my very first days. Catalonia is my place on earth.”
His final game for the club will be at the Spotify Camp Nou against Real Betis on Sunday, with Barca ending their campaign the following Saturday at Valencia.
Coach Hansi Flick, who also coached Lewandowski at Bayern Munich, has confirmed Lewandowski will start against Betis.
“He spoke with the team, said goodbye, and that it was a great time for him here in Barcelona,” said Flick.
“I’ve worked with Robert now for years, and we won together nine [trophies] – all the titles I’ve won were with him.
“For me it’s a privilege to work with him. He’s a professional player. Every day he gave the best with his body to be at the highest level.
“He’s a perfect role model for young players – a fantastic human, but also a world-class player. This is why he’s still playing at this level.”
Barcelona also paid tribute to the forward in a statement as they added: “Thank you, Robert Lewandowski, for every goal, every [bit of] fight, and every magical moment wearing these colours. He arrived as a star, he leaves as a legend.”
