ROQUE Santa Cruz sends shivers down Roy Keane's spine.

The 26-year-old Paraguay international's goal at Blackburn on Sunday was his 14th of the season and eighth in five games, and the Sunderland boss knows just what a threat he will be.

Asked if his defenders face another tough test, Keane said: "Of course they will, especially away from home against a good Blackburn team.

"They have got a centre-forward in unbelievable form - but every team you play in the Premier League has got top players.

"At the end of the day, we are up against, top-quality players."
