BARCELONA - Lionel Messi ended intense speculation about his future on Friday by saying he will remain with Barcelona for another year. The Argentine six-time world player of the year had told the club last month that he wanted to leave, insisting a clause in his contract allowed him to do so on a free transfer. Barcelona, backed by La Liga, have insisted that a 700 million euros ($824 million) release clause would have to be paid. “I wasn’t happy and I wanted to leave. I have not been allowed this in any way and I will stay at the club so as not to get into a legal dispute. The management of the club led by Bartomeu is a disaster,” Messi told website Goal.com.
