If Leeds United fans were not already fired up for Sunday's derby against Sheffield Wednesday, then Pontus Jansson is sure to get them ready and raring.The defender, who joined the Whites on a permanent deal in the summer, has been speaking to the media ahead of this weekend's Championship clash.There is always pressure on a derby match to deliver, but there is added weight on this one given that Leeds have lost two of their last three matches.The club were unbeaten in their first seven league outings, but they have since hit a slight rocky patch.Thomas Christiansen's side dropped to third in the table when they were beaten 3-1 by Cardiff City in midweek and they also went a man down when Liam Cooper was sent off.This Sunday's encounter has been made even tougher by the fact that Leeds are away from home against the Owls.Despite Jansson only being at the club for over a year, he is well aware of the importance of the fixture and insists that the team will fight like "animals".
