Madrid: Antoine Griezmann grabbed a stoppage-time winner as Atletico Madrid maintained their 100 per cent record in Champions League Group D with a 2-1 win over Rostov at the Vicente Calderon Stadium.

Griezmann opened the scoring with his first goal of the Champions League season but they were pegged back almost immediately by Iran international Sardar Azmoun. And just as it looked like Diego Simeone's side were going to be frustrated, Griezmann popped up with the last-gasp winner.
