Brad Guzan says Boro have the quality and belief to get a result against Manchester City this Sunday.
The US international has featured in Boro's last three matches following injury to Victor Valdes.
And after a confidence-boosting midweek win against Sunderland, Guzan says it's up to Boro to kick on with four top flight matches remaining.
"We knew it was a massive game, being a local derby, and we wanted to give the fans something to cheer about," the goalkeeper said.
"It wasn't the prettiest of games to watch but for us it was all about the result.
"At the end of the night, walking away with three points was huge for us.
"Hopefully on the back of this result, it will mean we can go into the last few games and do something special."
Having made sporadic appearances between the posts this season, Guzan says he's enjoying a run of games now and the challenge of helping Boro avoid relegation.
"With goalkeepers, you always have to be ready. If you're given your chance late in the season so be it," he said.
"When your name and number is called, you want to be counted on and help the team be successful.
"With the run of games now and hopefully until the end of the season, we can pick up some points and I can contribute to that."
Guzan suffered relegation from the Premier League last season with Aston Villa, but says there's a different feel at Boro.
"Throughout the squad, there's a determination to put things right," he said.
"You take belief from the way you train. Monday to Friday we're pushing each other and working hard, and on top of that you can see the quality.
"There's probably not too many people on the outside giving us a chance but we're believing inside our dressing room.
"First and foremost you want to do it for the club and the fans. That extra bit of motivation comes from wanting to prove people wrong."
The experienced stopper says Boro will be taking it one step at a time in a tough run of fixtures, starting with the visit of Pep Guardiola's side on Sunday.
"The teams we will come up against are very good, and are all fighting for things," he said.
"But at the same time, we're fighting for our lives and we'll give it everything we have.
"With any relegation battle you have to approach each game individually, and focus on your game.
"If you don't take care of business yourself then it doesn't matter what any other team does.
"Manchester City are a top team. We know there's going to be stretches we have to defend and be difficult to break down.
"But when we played them [in the FA Cup quarter final] we were able to create chances - it's a matter of taking them. If we do that we give ourselves half of chance."
