PARIS (Reuters) -Lionel Messi joined star-packed Paris St Germain on Tuesday after leaving Barcelona, the club where he had begun and expected to end his career. "I am excited to begin a new chapter of my career at Paris Saint-Germain," PSG quoted Messi as saying. The arrival of Barcelona's record scorer, with 672 goals, will boost Qatari-owned PSG's ambitions to win the prestigious, and lucrative, European Champions League for the first time. Messi will wear the number 30 shirt, the club confirmed in a video posted on its Twitter feed, headlined "a new diamond in Paris". Messi, who won four Champions Leagues and 10 domestic league titles with Barcelona, joins several other big names arriving at PSG on a free transfer this summer.
