Tottenham Hotspur midfielder Sandro has backed fellow Brazil international Oscar dos Santos to flourish at Chelsea.
Having completed his £25m switch to Stamford Bridge, Oscar is currently competing for Brazil at the Olympic football championships.
"He's a very good player, versatile, quick, and can play for any team in the world," commented Sandro.
"He can adapt wherever he goes. He's a big friend of mine too, so I will back him to succeed wherever he is."
Oscar impressed in Brazil's opening Olympic fixture, setting up two goals against Egypt.
