FK SARAJEVO handed Celtic a European warning by destroying Albanian champions Partizan Tirana 5-1 in a friendly.

The Bosnian side are currently in Slovenia in a training camp preparing to face the treble treble winners in the Champions League first qualifying round.

They shrugged off a delay receiving their wages from their Vietnamese owner and the threat of a players' strike to hammer Partizan in a friendly.

They romped to a 5-1 win with the goals coming from a double from Benjamin Tatar and Mersudin Ahmetovic, Aladin Sisic and Alen Mustafic.

And Sarajevo manager Husref Musemic was delighted with the performance.

He said: "We can all be very satisfied with this win and we look in good shape for the matches against Celtic.

"There is plenty of work to be done, but it's a good start against a side who are the champions of Albania."
