Robbie Keane feels that Blackburn's principal threat on Sunday is likely come from his Republic of Ireland team-mate Damien Duff.
Duff returned from injury in Monday's 2-0 victory over West Brom at the Hawthorns and will have Spurs in his sights as Rovers seek to overhaul us in the table at Ewood Park.
Keane warns to watch out for Rovers' lethal leftie.
"He is the main threat," says Robbie. "He got injured in the last Irish game, but he came back against West Brom in the week and showed what Blackburn were missing. He got the penalty and scored the goal.
"He's a tremendous player and Blackburn did very well to hold on to him. There were big clubs looking at him.
"He is a massive, massive player for them, a great lad as well and it will be nice to see him. Hopefully he doesn't play too well on Sunday."
International duty looms for both Keane and Duff as the Republic of Ireland seek to get their Euro 2004 qualifying campaign back on track against Switzerland at Lansdowne Road, having suffered a 4-2 reverse against Russia.
Keane reasons that, despite their tender years, himself and Duff are the more experienced campaigners in the Irish set-up following the retirement of Niall Quinn and Steve Staunton.
"Me and Damien have been lucky to have been given the chance to play international football at 17 or 18. We are considered the most experienced players in the squad rather than youngsters.
"There are players involved now who have about ten caps and me and Damien have around 30 to 40."
