Dean Whitehead fears he and his Stoke team-mates are soft targets for referees, after their physical style of play has come under scrutiny.[LNB] Whitehead picked up his fifth booking of the season last weekend, which has ruled him out of his side's clash with Manchester United.[LNB]Whilst very disappointed, the midfielder accused the referees of being too harsh on his team, as a direct result of what has been said in the press.[LNB]"I've no idea (why I was booked). I seemed to be the one getting pushed around, but all of a sudden I'm the one he booked," Whitehead said.[LNB]"I knew straight away it meant missing the United match.[LNB]"It was inevitable the suspension would come at some point, but I've got to say that two or three of the bookings I've got this season have been soft.[LNB]"Being at the club we are, and with a lot of talk in the Press about us at the minute, maybe we don't get as many chances off the refs as the bigger teams do.[LNB]"Our first foul is often a booking for our players, but other teams get two or three chances."
