Ronald Koeman is keen to bolster his options at Barcelona with some January additions, but he acknowledges the club's financial situation may make it too difficult.
Philippe Coutinho last week joined Ansu Fati, Sergi Roberto and Gerard Pique on Barca's long-term injury list, while Carles Alena was allowed to leave for Getafe on loan until the end of the season.
Koeman has already expressed his desire to add a striker to his ranks, with the club having let Luis Suarez leave in the close season without signing a replacement, and they continue to be linked with Memphis Depay.
