Last year's champion Shahjalal and runner-up Jibon Boli did not participate in this year's competition
Angel Correa fired Atletico ahead in the 23rd minute at the Calderon when Antoine Griezmann cushioned a delightful pass into his path and he cracked the ball past Julio Cesar from close range.
Nicolas Gaitan levelled for the visitors in the 36th minute, smashing a first-time shot through a crowd of players, and teenager Goncalo Guedes made it 2-1 six minutes into the second half when he converted a Gaitan cross at the far post.
They were the first goals Atletico had conceded at the Calderon in Europe’s elite club competition in more than 700 minutes and prevented them from setting a Champions League record of eight consecutive home clean sheets.
