Thiago Silva’s eight years as a Paris Saint-Germain player are about to come to an end and the Brazilian centre-back has one piece of unfinished business to contend with as the Qatar-owned club head to Lisbon targeting Champions League glory. That is something that has so far eluded Silva and PSG, despite all the money Qatar Sports Investments have ploughed in. “I have seen everything here. This competition is so important, for the players but also for the club. Winning it was the objective when I came here,” Silva, whose contract is about to expire, said in an interview with AFP.
