Denis Suarez's agent Felix Gende has suggested that Barcelona will not grant the outcast midfielder a move away from the club next month.
Suarez, restricted to appearances in cup competitions this term, admitted after Barca's Copa del Rey win over Cultural Leonesa - a game in which he scored twice - that he is unhappy with his lack of minutes.
Amid talk of Chelsea preparing a cash offer for the Spain international, however, agent Gende has cast doubt on a mid-season exit.
"I think it is difficult for Denis to leave FC Barcelona this winter, either by means of a loan or a transfer," he told Fichajes
"Marseille has never called us. It's a complicated situation, but he has confidence in his work to reverse the trend."
Suarez rejoined Barcelona from Villarreal in 2016 and has made 44 La Liga appearances for the club.
