Dortmund must improve on last week's performance to win at PSG says Terzic

Borussia Dortmund have a 1-0 lead going into the second leg of their Champions League semi-final at Paris St Germain, but to win the tie they would need an improvement in their performance, coach Edin Terzic said on Monday. Dortmund have never won at PSG in their previous three visits, and their last match at Parc de Princes ended in a 2-0 loss during the group stage in September.
