Thiago Alcantara says he couldn't turn down the challenge on offer at Liverpool as he said an emotional farewell to Bayern Munich.
The Spanish midfielder will put pen to paper on a four-year deal at Anfield as he leaves Bavaria after winning seven Bundesliga titles in seven years, while also picking up the Champions League in Lisbon last month.
Liverpool have been chasing the 29-year-old all summer, with Jurgen Klopp certain that he can bring something different to the Premier League champions' midfield.
Thiago will wear the No.6 shirt at Anfield, and could be in line for his Liverpool debut in next Thursday's Carabao Cup third round tie at Lincoln City.
In a video released on his Twitter account on Friday, the former Barcelona man said goodbye to Bayern and thanked everyone at the club.
"Yes, I have made the most difficult decision of my sports career," he said.
"I will close this chapter in this wonderful club where I have grown as a player for seven years.
"Triumphs, joy and also hard times.
"But what I am most proud of is that I arrived in Munich as a young man full of dreams and now I will leave completely fulfilled with a club, a history and a culture.
"Here I learned to love a tradition, that I am now saying goodbye to, but which I will never forget: 'Mia San Mia' (We are who we are).
