Swansea City boss Bob Bradley has pumped Gylfi Sigurdsson for information on former club Tottenham.
Bradley is more than happen to use input from his star man in plotting Tottenham's downfall.
"There's a little of that goes on. Gylfi has a good presence in the team. He's not the most vocal guy but he's well respected. He's a very good professional," said Bradley.
"As we get closer, we put together our video analysis and scouting reports.
"We always rely on players that have inside knowledge."
