Robbie netted his 14th goal of the season at St James Park, but his strike failed to really alter the course of events and the home side responded with a further two before the break and secured a 3-1 win.
The current form of the new Republic of Ireland skipper offers great encouragement for the run-in, with the 25-year-old having scored seven goals in as many games. He was, however, a little reluctant when it came to assessing his contribution to the cause.
"I'm doing okay, doing as well as I can for the team and that is the most important think," he reflected modestly. "I've been lucky enough to score a few goals, but the team have been doing well apart from last Saturday.
"That is gone now and we must move onto the next game," he added, before admitting goals have got his confidence flowing.
"Of course there is confidence, when you feel like this goals seem to go in a lot easier than at other times. Things are going well for me personally, but it is not about me, it is about winning.
"I scored on Saturday, but it doesn't feel good when you lose. We want to put it right now against City and get that winning feeling back."
The visit of City on Saturday is our third last home game of the season and Robbie knows the taking of significant reward from these matches will prove vital towards our finishing line ambitions.
"It will be, there are not many games left and it is important to stick in there because we know Arsenal are flying at the moment with a game in hand.
"We will concentrate on ourselves and not worry about anyone else. Hopefully, come May, we will be where everyone wants us to be.
"City are a good side who have struggled a bit recently. They've got good players and a manager like Stuart Pearce will get them right up for the game.
"I saw him interviewed last week after the Middlesbrough game and the players will want to prove to the manager what a good side they are.
"We've got to be wary of that."
The in-form Robbie Keane is hoping the team can put right last weekend's setback against Newcastle when Manchester City arrive at the Lane on Saturday.
