Former Gremio president Fabio Koff believes Luiz Felipe Scolari will bring great success to Chelsea.
"He is a modest man," revealed Koff, the man who appointed Scolari as Gremio's coach for a second time in 1993.
"We had a relationship which went above and beyond that of president and manager. When he went to Japan he wasn't happy, so I helped him get the job at Palmeiras and he won the Copa Libertadores again.
"When he was asked about Chelsea he had three offers. He called me in May and asked me what I thought. I told him to go for it. He loves a challenge.
"He will win trophies in England. Manchester United are exceptional but Chelsea will be a much better team under Scolari. They will play a Brazilian style and he will bring in Brazilian players. That is going to happen.
"He always calls me for advice. I tell him he is my son, but my wife always says to him: 'You're not my son!'."
