GLASGOW (Reuters) - The dazzling Lionel Messi returned from illness to score yet another double to help Barcelona ease into the knockout stages of the Champions League for a 13th successive year with their 2-0 win at Celtic on Wednesday.

Messi, who missed the goalless draw with Malaga on Saturday with a sickness bug, was back to his tormenting best just as he had been when scoring a hat-trick in Barca's 7-0 win in the their Group C fixture at the Nou Camp two months earlier.
