Lionel Messi will lead the FC Barcelona attack when his side entertains AS Roma in the first leg of their Champions League quarter-final on Wednesday night. The Argentinean only played 30 minutes of Barca's 2-2 draw away to Sevilla on Saturday due to a groin injury, but showed how important he is as he led their fight back from 0-2 down, lifting their confidence the moment he stepped onto the pitch, reports Xinhua news agency.
