Oliver Giroud card costly as Arsenal fall at opening hurdle

Dinamo Zagreb 2 Arsenal 1: Zagreb was hit by an earthquake on Tuesday night and perhaps that was an omen for the Gunners who had striker Olivier Giroud sent off as they slumped to a disappointing 2-1 defeat in their Champions League Group F opener at Dinamo Zagreb.

The France forward missed a couple of early chances before collecting two needless cautions in the first half.

Dinamo took the lead against the run of play with an own-goal from Alex Oxlade-Chamberlain after the ball bounced back off him past goalkeeper David Ospina, who had saved Josip Pivaric’s shot.
