TBILISI, Georgia (AP) — Lionel Messi scored twice and set up the winning goal as Barcelona started the season in dramatic style by beating Sevilla 5-4 after extra time to lift the UEFA Super Cup on Tuesday.The action-packed, all-Spanish match was won when Pedro, linked by British media with a move to Manchester United, scored from close range after a shot by Messi rebounded in the 115th minute.In the final seconds of extra time, Sevilla defender Adil Rami had a golden chance to send the match to penalties but missed an open goal from close range.Earlier, Sevilla had battled back from 4-1 down to 4-4 as Barcelona's fitness was tested in its first competitive match of the season - Europe's curtain-raiser between the winners of the Champions League and the second-tier Europa League.After a busy pre-season with games in the United States, Italy and Spain, Barcelona's dominance evaporated midway through the second half."I thought we were much better, much stronger," Messi said of the first hour of the match.
