Middlesbrough head coach Kim Hellberg paid tribute to his team's defensive side as Boro hung on to beat in-form Norwich City.
The home side survived mounting pressure in the second half as they held on to win 1-0 thanks to Hayden Hackney's 17th-minute long-range strike.
A 17th win of the season lifted Boro level on points with Coventry City and behind the Championbship leaders on goal difference as the Sky Blues were beaten at QPR.
"The last five minutes of this game were in some ways the ugliest thing I have seen on a football pitch and in some ways the most beautiful thing," he told BBC Radio Tees.
"It was passion, everyone involved. The crowd was unbelievable, the players understood everything in terms of playing the way we needed to play in those five minutes, so I think that was very, very beautiful and something very special.
"It felt like it wasn't our best day with the ball but then [it's about] how you defend like that in the second half. That is against a team that has done four wins in a row.
"How you defend with that heart and that passion and doing that together and still keeping them away from clear chances – the passion and the energy, that's what I'm going to take away with me. It was unbelievable."
