Barcelona legend Hristo Stoichkov says that his former club need to sign at least two players in the summer.
The Catalan side are going through a rough period, finding themselves four points behind league leaders Real Madrid with just five wins in their last 10 games.
The run of poor results has seen coach Gerardo Martino come under a great deal of pressure but Stoichkov insists that the Argentine is not the only one to blame.
"It's very easy to lay the blame at his door," the Bulgarian told Marca. "He doesn't hide from it. I don't think he's overwhelmed. These bad results can be fixed in the dressing room. That's where the team can get a lift.
"We need two or three players to reinforce this side and we shouldn't force the players from Barca B to go to other clubs to find glory."
The former Barcelona forward went on to discuss the Blaugrana's recruitment policy, arguing that the club must trust their current staff to carry out the rebuilding process.
"I have a great deal of respect for [Andoni] Zubizarreta and I'm not going to criticise him for a second," Stoichkov added. "If he's left to get on with it, he knows what he's doing. He wants one guy and they get him someone else. That didn't happen with Txiki Begiristain."
The 48-year-old was then asked if he thinks that current Atletico Madrid boss Diego Simeone would a good coach for the Catalan side but replied: "Cholo would be too much for Barca."
