NIGERIAN midfielder Sunday Oliseh was on Tuesday signed by German Bundesliga football side Borussia Dortmund from Italian club Juventus Turin. The 1997 Champions League winners, who were just five points from relegation to the second division last season, paid a $7,5 million (DM 15-million) transfer fee for the 25-year-old Nigerian skipper. Oliseh signed a five-year contract as Dortmund’s first major off- season addition. He returns to the Bundesliga after playing with FC Cologne from 1995-97. Oliseh also played with Ajax Amsterdam before heading to Turin, where he did not play regularly.
