Afterwards Pozzi and other medalists spoke to the media and below is what they had to say.
"I could see I was behind Jarret (Eaton) but I was fixated on the line and had to drive towards it as best I could.
"To be a world champion in Birmingham makes the achievement tenfold. I've grown up here over the last decade. The first competition I ever watched was the trials here 15 years ago.
"My heart stopped at the end. I knew I was behind and I can't describe how much I wanted it. I was throwing my body at the line and I just about got there.
"These championships have been amazing and to be captain for these championships is the biggest honour of my life. Every member of this team has been perfect and I'm delighted I could do it.
"In every interview I've said I was in great shape and I didn't come in with the fastest time, I was 10th or 11th. So to come out and win with a great time is perfect.
"There is no way I could turn down coming to Birmingham. It's the World Indoor Championships and to win is an absolute delight.
"These moments have kept me going (through all the injuries). I knew I could come back out and get to the very top.
(On winning on the day of Roger Bannister's death)
"Roger Bannister was an unbelievable athlete and unbelievable person. I'm very sorry that he has left us but I read one of his quotes today about a gazelle before heading down to the track. It said: 'Every morning in Africa a gazelle wakes up and it knows it must move faster than the lion or it will not survive.'"
Jarret Eaton (USA) – Silver
"It's amazing to win this medal. It was great race out there but silver means more training and more work to do."
Aurel Manga (FRA) – Bronze
"It's awesome. It's my first medal. We've worked hard for this but tomorrow it's back to work again for the rest of the season.
"I will celebrate with my coach tonight, but tomorrow we'll go back to France and get back to work."
