Paris Saint-Germain defender David Luiz has warned Chelsea they wo n't achieve success by simply sitting back when the two sides meet at Stamford Bridge on Wednesday . The first leg of the Champions League tie ended 1-1 , meaning a goalless draw would be enough to send Jose Mourinho 's side through to the next round . But Luiz , who spent three years in west London before his £50million summer transfer to PSG , said it would be foolish of his old club to invite pressure on themselves considering the strength of the Ligue 1 champions ' attacking options . David Luiz has warned his old club Chelsea of the dangers of simply sitting back against Paris Saint-Germain . Luiz spent three years in west London before his £50million summer transfer to the French champions . ' I know how Jose ( Mourinho ) will prepare for this , he will be telling the boys to be patient and hit us on the counter attack , ' Luiz told The Mirror . 'He knows that we need to score and that they do n't , I know that is his way . We must be careful because I know that Chelsea have the ability to hurt on the counter attack , but they must be careful as well . 'To sit back and just defend against Zlatan ( Ibrahimovic ) , ( Edinson ) Cavani and ( Ezequiel ) Lavezzi can also be very dangerous , so it is not just us who have to be careful . ' He added : 'We have players that are used to big occasions , and playing in big stadiums , we know we can do this . ' Edinson Cavani scored against Chelsea when these two sides met in February at the Parc des Princes . Branislav Ivanovic gave Chelsea the lead in the first leg of the Champions League tie at Parc des Princes .
