Osasuna coach Peter Vasiljevic has claimed that his players might need "handcuffs and a pistol" to stop Lionel Messi, ahead of his side's clash at the Nou Camp on Wednesday night.
Vasiljevic's side currently sit bottom of La Liga, nine points from safety with relegation looking an inevitability.
Barcelona, meanwhile, went top with a dramatic Clasico win over Real Madrid at the Bernabeu last weekend, a game in which Messi's brilliance inspired them to a late victory.
"I've already said that we need a plan for Messi and the players told me [that we need to] carry handcuffs and a pistol,” Vasiljevic told Marca.
"When he's inspired, he's a genius. He disconnects, but later he plugs [himself] in for 10 minutes and does what he does."
Messi was bloodied and bruised against Real Madrid on Sunday, but performed exceptionally and scored a brace, which suggests a pistol and handcuffs may not even be quite enough to stop him.
Osasuna have conceded the most goals in La Liga this season, 75 in total, while Barcelona have scored a prolific 94.
The signs are certainly not promising for Wednesday night's visitors, but perhaps they might spring a surprise with what they have planned for Messi.
Let's hope violence is avoided, though.
