AS Roma chief Walter Sabatini says there's no plans to sell Marquinhos or Pablo Daniel Osvaldo.
The pair have been linked with moves away.
"We won't be selling our best youngsters, all of them will be staying," said Sabatini.
"As for Osvaldo, he is the Roma centre-forward. I repeat that we want to keep our best players, then we'll have to see what the players themselves want.
"We, however, do know that we can improve the squad."
