Middlesbrough manager Gareth Southgate praised teenager Seb Hines after watching his side survive a spirited Hull City fightback to eventually reach the fourth round of the FA Cup.
The 18-year-old debutant opened the scoring as Boro eased into a 3-0 lead early in the second half, but the Premiership side had to survive a nervy finale before eventually beating the Tigers 4-3 in the third round replay at the Riverside Stadium.
"I'm delighted for Seb," Southgate said after the seven-goal thriller. "The one concern about playing him was that he was out of position, he's far more comfortable at centre-half or right-back.
"But he was very level-headed and the goal was a bonus.
"For the first hour we played very well and I was delighted. I wanted us to be bright and sharp and we were.
"And then, just as I was thinking of taking a couple of players off to rest them ahead of Saturday's game, we got a bit sloppy in defence.
"But I'm not going to hammer the lads. They're in the dressing room and it feels like a defeat for them because of the standards they've set themselves.
"We know we should have defended better in the second half but it's been one of our strengths this season. When a team has nothing to lose they just go for it and that's what Hull did."
Boro visit Bristol City in the fourth round of the competition later this month.
