The Argentine ace has reiterated switching clubs has never crossed his mind to date and is confident defeat to Bayern Munich in the Champions League will make his side stronger.
The four-time Ballon d'Or winner joined the Catalan giant's youth academy in 2000 and has won the Champions League three times and La Liga on six occasions since breaking through to the first team in 2003.
Speaking at a press conference in Qatar, the 25-year-old again stated that leaving the Blaugrana has not once crossed his mind.
"I never thought about playing anywhere else than this club," he told reporters.
Barcelona is on course to equal the record of 100 points in La Liga having clinched the title already, but the club suffered a humiliating 7-0 aggregate defeat to Bayern Munich in the Champions League - something which Messi believes will help to make his side stronger.
"Winning the league is very good though our goal is always to win everything," he added. "Bayern were the superior team this year, now we must prepare for next year."
