Argentinean midfielder Walter del Rio failed to impress Bruce Rioch in his trial spell at Carrow Road in the summer of 1999. The former Boca Juniors star was previously with Crystal Palace for whom he made 2 league appearances (one as substitute).

On 29th July 2000, it was reported that new Dundee manager Ivano Bonetti had invited Walter for a trial with them. Walter had been at Dundee earlier under Jacky Scott's regime. He signed for them and made 9 appearances in 2000/01. He was freed by Dundee at the end of May 2002.

Walter spent time in Italy with Carrarese and Cosenza before joining FC Wohlen. He is now with YF Juventus Zurich.
