The Magpies are looking to build on a positive result last weekend.
The Dutchman has been one of few at the club to have emerged with any credit over the last few weeks, and in the absence of Aleksandar Mitrovic, has become the Magpies’ most potent attacking threat, despite his right-back position.
Saturday’s draw with Chelsea demonstrated a fight and desire that has so far been lacking in Newcastle’s performances, and Janmaat feels the squad can take confidence from the result.
“Hopefully, it (the Chelsea game) has answered a few questions,” he said, in quotes published by the Sunderland Echo.
“There have been times this season where we have shown it is in there – we just need to do it on a much more consistent basis now.
“Maybe everyone has to believe in themselves a little bit more because we have shown we can do it. If the belief is there, then I’m sure the wins will come too,” he added.
Steve McClaren’s men have drawn with Manchester United and Chelsea this season, while a dismissal helped Arsenal shade things at St James' Park, suggesting the team is better suited to the underdog role.
West Ham United are a similar case, in that they have recorded three excellent away wins against some of the league’s biggest teams, but have struggled in games they are expected to win.
The Newcastle squad doesn’t cope with the weight of expectation well, and that could point towards a positive result this weekend.
All bets will be on a comfortable Manchester City win, but a disciplined and compact Newcastle side, with the dynamism of Perez and Mitrovic up front, could yet spring a surprise.
