Owen Coyle praised the performance of on-loan winger Ryo Miyaichi after the teenager starred in Bolton's 2-0 win against Millwall in the FA Cup fifth round.
The Scot singled out the Japanese youngster after he opened the scoring in the fourth minute with a curling effort.
Wanderers sealed the tie just before the hour mark thanks to David Ngog's long-range effort, but Coyle was delighted with the display from the Arsenal loanee.
"His second-half performance against Wigan last week was terrific, and from that moment there was no doubt he was going to start today," he said.
"He showed what a talent he is. There's other stuff he can learn, but he's brave and tough - he stood up to some of the treatment he got today - and he always plays with a smile on his face, which I absolutely love.
"First and foremost I am a football fan and I want to be excited by some of the players I've got in my team, and Ryo Miyaichi certainly does that.
"In football terms he is a baby, a kid. I saw when Arsenal brought him in and then watched him on loan at Feyenoord last year, and he always caught my eye.
"I spoke to Arsene (Wenger) a few times about him and did everything I could to get him to the football club."
Coyle was pleased with his side's determination at The Den in what he expected to be a tough tie.
"I know from both my playing and coaching days how difficult any cup tie can be," he said.
"I've been an underdog many, many times. I think we started well. It probably took Millwall 15 or 20 minutes to get into the game, but when they did they had a few corners and a bit of pressure.
"We stood up to what was always going to be a difficult test. We defended well - Tim Ream had a terrific debut."
