Borussia Dortmund beat AC Milan 4-0, and Feyenoord Rotterdam topped Internazionale of Milan 1-0 Thursday in the UEFA Cup semifinals, making an all-Milan final very unlikely.

The Italian clubs are trying to be the tournament's first two finalists from the same city.

In Milan, Colombian defender Ivan Ramiro Cordoba deflected a low cross by striker Pierre van Hooijdonk into his own net, allowing Feyenoord to move closer to its first European title since the 1974 UEFA Cup.

The game marked the return of Internazionale's Brazilian striker Ronaldo after a 102-day injury layoff.

This year's UEFA final is May 8 at De Kuip Stadium _ Feyenoord's home field.

In Dortmund, Germany, Marcio Amoroso scored three goals for Borussia, which hasn't been to a European cup final since it won the Champions Cup in 1997.

Joerg Heinrich had the hosts' other goal.

``The first half was very good, almost perfect,'' Dortmund coach Matthias Sammer said. ``Marcio was hot. We need him, we need his goals. We played very well, and Milan was perhaps a little bit surprised.''
