Papiss Cissé has been in sensational form since joining the Magpies in January, netting 13 goals since his winter move from Freiburg.
And City defender Richards is wary of the threat posed by the Senegalese forward, who fired Alan Pardew’s men to victory with a stunning brace at Chelsea in midweek.
“They’re a really good side and I think Demba Ba and Papiss Cissé are going to be a real handful,” Richards, 23, told City’s website.
“I think Vinnie [Vincent Kompany] is going to have to follow Cissé around and stick to him like a leach because everything he tries at the moment seems to come off.
“His two goals at Chelsea were world class and Nigel de Jong knows what he’s capable of because I think he’s been up against him a few times in Germany. He says he’s always been a goal-scorer so he’ll be a threat.”
Richards added: “They have other talents like Yohan Cabaye – but we will have eleven fantastic players that Newcastle will be worrying about and we know if we are at our best, we can beat anyone.
“Newcastle like to play attacking football, too and we always seem to play better against teams like that because it suits our style.
“We’re in good shape, we all want to play, but I can’t see how the manager could change a team that has played so well and I don’t know why he would want to, either.
“Training has never been better, the lads are in great spirit and it doesn’t matter who starts because whoever plays, they will give their all to try and get us over the finishing line.”
Premier League leaders City go into Sunday’s clash ahead of title rivals Manchester United on goal difference with two games left to play – and Richards admits the pressure is now back on the Citizens.
“In some ways it was easier when we were chasing United because at one point, we were down and out in many respects,” he continued.
“We had nothing to lose and the pressure was off, but now we have two must-win games starting on Sunday at Newcastle.
“The situation has not really changed that much because we needed to win our last six games to stand any chance of catching United and now we’ve drawn level with them but there’s still so much hard work to do.”
