Udinese director of sport Fabrizio Larini says either Alexis Sanchez or Gokhan Inler will leave this summer, but not both.
Sanchez is attracting interest from Inter and Chelsea after yet another stellar performance in Serie A at the weekend.
The Chile international winger scored four goals in a 7-0 rout of Palermo under the watchful eyes of a scout from Barcelona.
Meanwhile, Inler is known to be Napoli's No 1 priority once the transfer window opens again at the end of this season.
Speaking to Radio CrC, Larini said: "We will evaluate where we are at the end of the season.
"We'll see how to behave in the transfer market.
"In any case, it's logical that we will not sell more than a certain number of players.
"Only one out of Sanchez and Inler might leave, but not both," he concluded.
