Sibierski Ready For Pearce And His Boys
Last season Pearce dropped him from the first team squad and Glenn Roeder brought him to Tyneside on a free transfer.
The 32-year-old Frenchman was allowed to leave Eastlands and the Frenchman left with a blast for his former boss, after Pearce said he had lost patience with him three years after his £700,000 move from Lens.
Sibierski: "Stuart Pearce has shown he is a human being by getting on with his job. He is the same as us, we are under pressure and we have to do the same as him.
"I want to do well against my old club. The first thing, though, is we need to win for our team and for our fans to be happier.
"Personally, I will be very, very happy to beat them - but Newcastle comes first.
"We have to work hard collectively and personally. It is always hard when you lose as a group, but that is the way it is. Even if you do some good things as an individual, you are usually judged as a group. That's frustrating but, as players, staff and for the fans, the situation is not easy.
"We understand the fans feel bad and we know we are not doing well. We have to keep working and prepare very well for the Manchester City game."
