Arsenal face a struggle to finish top of their Champions League group after they were held to a draw by Paris St-Germain at Emirates Stadium.
The Gunners were seeking the win that would put them in pole position in Group A after years of finishing second and six eliminations in the last 16 in the knockout phase.
And it looked like Arsenal were on their way despite going behind early on to Edinson Cavani's sliding finish from Blaise Matuidi's cross.
Olivier Giroud scored from a penalty right on half-time after Grzegorz Krychowiak fouled Alexis Sanchez. And Arsenal were ahead on the hour when a penalty-box rebound struck Marco Verratti and flew in.
