Jordan Rhodes says his goal against Queens Park Rangers at Loftus Road in April is one he looks back on as a personal confidence booster before the season's run-in.
The striker joined Boro in January and scored five goals in his last eight games to help push Aitor Karanka's side over the promotion line into the Premier League.
Boro played Sunderland in a behind-closed-doors friendly during the March international break when Rhodes scored the winner and the striker points to that goal as an important one before heading to QPR a week later.
"Firstly I would've liked to have contributed a few more goals, I certainly had the chances in games to make it a little more comfortable for us," said Rhodes.
"But those things never happened and I went a few games without scoring. I look back on that one down at QPR as a particularly nice one to see go in.
"We had a bounce game against Sunderland the week before and I managed to score so it gave me a bit of confidence and strikers play off that.
"There were some Premier League players on show at the time and on paper it doesn't really mean too much, but it did to me.
"It was nice to get a few but I would've liked to get a few more. It wasn't about me, though, it was about Middlesbrough Football Club getting promotion back to where it belongs in the Premier League.
"I said the QPR goal boosted my confidence a little bit, but certainly scoring in the last minute at Bolton was also great.
"I was happy to tap it in but Dave Nugent did so well coming on to tee me up. That was a special feeling and nice because we had a period of scoring last minute goals. It was nice to see that one go in."
Close to 4,500 Boro fans made the trip to Bolton that day and Rhodes believes the travelling Teesside support played a big part in the number of late goals the team scored.
"The fans have really taken to me and been fantastic since the day I came in the building," said the striker.
"The backing that we've had both home and away has been absolutely incredible - it's the best in the league.
"It really has helped us and I don't think it's any coincidence that when we've scored the late goals we have it's almost been because the fans have cheered the ball over the line.
"That backing has been fantastic and we're going to need it even more next season."
