Matthäus sees a bit of himself in Vidal
The former West German World Cup-winning captain was speaking at a press conference in Berlin between the Bundesliga and Fox Sports to announce the league being broadcast in over 70 territories – including Singapore – for the next five years.
"I think Vidal is a player who can make a difference at the highest level," said Matthäus, who made his name at Bayer Leverkusen before winning seven Bundesliga titles in two spells with Bayern Munich.
"He has experience, he knows German football because he played for Leverkusen, and now he has experience with Juventus where he won the title four times and with Chile in the Copa America."
Vidal moved to Bayern from Serie A champions Juventus for £24.8 million and won the Copa America with Chile just last month.
"[He] is a key transfer for me and is a very good player," Matthäus said.
"I was thinking weeks ago that Vidal plays like me 20 or 30 years ago. He's a very aggressive box-to-box player, a No.8 player.
"Munich missed a player like Vidal in the last two or three years because he's very aggressive, he has good technique, he's strong, he's pushing the team and he's a brilliant leader."
Matthäus believes that his signing can only be a good thing for Bayern and the Bundesliga and comes at a time when German football is on the rise.
"We get superstars from many countries, like Vidal, the best player in Chile," he said.
"He's not playing in England, he's not playing in Italy, he's not playing in Spain, but he's come to Germany instead and is an upgrade to German football."
His thoughts were echoed by Bundesliga chief executive Christian Seifert, who hailed the importance of the new television deal with Fox.
"We are pleased to embark on a journey with such an important, global-scale partner that provides German football even more opportunities for worldwide exposure," Seifert said.
"The partnership with Fox confirms the international importance of the Bundesliga and its continuous international growth."
