The Brazilian star suggests the European champions will be favourites when they face Los Rojiblancos on Friday, but team-mate Juanfran remains upbeat about their chances
Los Rojiblancos will be contesting the tie for the second time in three seasons, having beaten Inter 2-0 in the 35th Super Cup in 2010 and will also be in buoyant mood after thrashing Athletic Bilbao 4-0 on Monday.
The Brazilian defender told AS he did not believe this made the Spanish team favourites, however: "Chelsea have everything to gain, but even though we lost Diego, we have a very strong team and ambition.
"I was at the club for the last Supercopa, but I did not feel right for not having been to Hamburg [where Atletico won the Europa League final].
"Now I feel good," he added. "I was very scared of missing the final after the last injury I had."
Team-mate Juanfran, however, held the view that anything can happen and that Chelsea were by no means favourites to succeed on the night.
"There are no favourites, there are many possibilities," he said.
"At Chelsea, I like Torres and Mata, with whom I've been speaking about the game since the Euros. They are great people and I wish them well, but only after the game."
