Messi goes missing as Barca crashes out

Argentine striker strangely subdued in clash with Atletico

When the dust settles on Wednesday's shock Champions League exit at the hands of Atletico Madrid, one question on the lips of many Barcelona fans will be: where was Lionel Messi?

The Argentina forward and four-time World Player of the Year barely threatened the Atletico goal at the Calderon as Barca fell behind to Koke's fifth-minute volley and was unable to turn around the 2-1 aggregate scoreline.
