( CNN ) -- Hamburg have put one foot in the UEFA Cup final after a header from Germany winger Piotr Trochowski proved enough to give them a 1-0 win at Bundesliga rivals Werder Bremen in the first leg of their semifinal . Piotr Trochowski celebrates the only goal as Hamburg took a major step towards the UEFA Cup final . Martin Jol 's side scored the only goal of a pulsating match in the 38th minute when Trochowski , the smallest player on the pitch , rose superbly at the back post to head Guy Demel 's right-wing cross past goalkeeper Tim Wiese . Both side had countless half-chances to score but Hamburg wasted the best of them on the hour mark when Bayern Munich-bound striker Ivica Olic broke through in acres of space , but fired his shot straight at Wiese . Hamburg 's victory puts them on line for their first European final since 1983 , when they beat Juventus 1-0 to win the European Cup . This was the second of four matches in quick succession between the north Germany neighbors -- who met each other in the German Cup last week and will play the return leg of the semifinal next Thursday before a Bundesliga clash on Sunday May 10 . And the result was sweet revenge for Hamburg , who saw Wiese save three penalties in last week 's shoot-out as Werder knocked their rivals out of the German Cup , also at the semifinal stage . The eventual winners will play either Shakhtar Donetsk or Dynamo Kiev in May 's Istanbul final .
