The Camp Nou giants are looking for a new shot-stopper this summer and the Malaga No.1 says only a "stupid person" would reject them
Current Barca No.1 Victor Valdes has announced his intention to leave the Camp Nou giants, with Monaco at the forefront of a queue of clubs vying for his signature.
Caballero, who has impressed throughout this season in La Liga and in his side’s surprise run to the quarter-finals of the Champions League, says the opportunity to replace Valdes would be too good to refuse for any top keeper.
Speaking to Spanish radio show Esports Cope, he said: “If Barcelona called me, I would not hesitate. I would not let the phone ring twice.
“Who would not like to play with these great players? Only a stupid person would say no to Barcelona.
"I hope Valdes can keep on demonstrating that he's a great goalkeeper wherever he goes on to play next year.”
The shot stopper’s impressive form for Malaga has led to calls for him to receive a chance with Argentina at international level and Caballero says he is confused by his lack of international opportunities to date.
The 31-year-old added: "I really don't know why I am not in the national team, but I would love to be there again.
“I know Mascherano as we played together in the Olympics. I barely know Messi, I’ve only been with him in some training sessions, but I get on well with everyone in the set-up.”
Malaga currently sit sixth in the table going into the final round of matches, where they face champions Barca - who are a victory away from reaching the 100-point milestone - at Camp Nou on Sunday.
