German legend Lothar Matthaus believes Arturo Vidal will make a big impact at Barcelona.
The former Bayern Munich midfielder moved to Barca last week.
Matthaus said, "Barcelona took a great player.
"He will undoubtedly be very important for them in the fight to win the Champions League. Arturo Vidal fits very well in the profile of FC Barcelona. He plays perfectly the 'tiqui taca'.
"He will be a real contribution for them in the competitions where they are engaged."
