Sergio Aguero is adamant that he will not officially sign for Barcelona until he knows whether Lionel Messi will stay at the club, according to reports.
Manchester City ace Aguero looks set to move to the Nou Camp this summer as a free agent and there were even indications that he would undergo his medical on Monday - just two days after the Champions League final.
But the situation now looks to have taken a twist at the 11th hour with Mundo Deportivo claiming that the green light will only come from Aguero when the future of talisman Messi is clearer.
