PARIS (Reuters) - Paris St Germain may have clinched their long-expected sixth Ligue 1 title in the last seven seasons but that triumph cannot mask the French club's shortcomings on the European stage where results have failed to match their huge investment.

Even the prospect of another domestic double -- PSG play Stade Rennes in the French Cup final next Saturday -- cannot soothe the pain felt by fans at seeing their galacticos again fall at the last-16 hurdle in the Champions League.
