"To be honest I am very happy", he told Barcelona's official website.
"He is a player with character, who gives a lot in the centre of the pitch, not only in defence but in attack".
'I don't have accounts to settle with anybody, just my objective, which is to win the Champions League, not settle scores with Real Madrid, ' said Vidal.
"It's down to my agent, but when he presented the option of Barcelona, I did not hesitate for a second".
Bayern was eliminated by Madrid in the Champions League quarterfinals in 2017 and in the semifinals in 2018. Hopefully I can win three". "I hope to achieve this goal here with Barcelona". With the confidence that the people have given me, I want to win it all.
Vidal also named the players he is most looking forward to working with at the Camp Nou next season.
"I have to be up to the task, because these are the best players in the world". "I am excited to play with Messi, [Luis] Suarez, Sergio Busquets... they are all great players", he added.
