Barcelona presidential candidate Victor Font has again urged them to complete the signing of Eric Garcia before the end of the January transfer window.
With no permanent president yet in place at the Camp Nou, the Catalan club haven't opted to pursue a deal for the Manchester City defender this month.
"Barcelona are not about to win a lot of things right now," said Ronald Koeman admitted on Saturday.
"Koeman's comments this lunchtime show the complete lack of a sporting project that the club has had for some time," presidential candidate Font said in response.
"One way of interpreting what he said, within the means of possibility, would be to sign Eric Garcia urgently to strengthen the backline."
With Gerard Pique out injured and Samuel Umtiti's fitness problems, Barcelona are fairly short in terms of defensive options. They can sign Eric Garcia for free - but not until the summer.
"[Garcia] is a signing that the coach and the sporting department are asking for because the Copa del Rey is getting to a decisive stage, the Champions League is coming up and Real Madrid are floundering in LaLiga," Font added.
"Between us all, we have to help in order to have the best team possible to challenge for titles this season."
