Sampdoria aim to close a deal for Everton striker Samuel Eto'o today.
The Blucerchaiti have an agreement with Eto'o to move to Marassi.
"We're very pleased with our position and we'll try to maintain it as long as possible," Osti told Telenord.
"Eto'o should be in Genoa on Tuesday, and also Muriel and [Andrea] Coda will be announced soon.
"Will [Stefano] Okaka and [Daniele] Gastaldello leave? All I'll say is that Sampdoria isn't a supermarket "
