After two straight home losses in the French league, which coach Carlo Ancelotti described as a crisis, Paris Saint-Germain's promising season will take a turn for the worse if it fails to win at Dynamo Kiev in the Champions League on Wednesday.

Despite big home wins against Dynamo Kiev and Dinamo Zagreb, PSG can still go out of Europe if it loses Wednesday and at home to FC Porto, and if Dynamo then wins its remaining match against Dinamo Zagreb.

That scenario seemed unthinkable when PSG routed a poor Dinamo side 4-0 two weeks ago, with Zlatan Ibrahimovic looking imperious. But confidence has been severely dented after Saturday's embarrassing 2-1 home loss to Rennes, which played most of the second half with nine men and a third-choice goalkeeper.
