Alex Mitchell couldn't hide his delight when speaking about his new contract to millwallfc.co.uk.
The 19-year-old put pen-to-paper on a long-term deal on Tuesday and capped off the day by making his senior debut late on during The Lions' 3-1 Carabao Cup Second Round victory over Cambridge United at The Den.
"It's a dream come true," the defender explained. "I'm grateful for everyone who has been a part of the process, including my family, who are buzzing for me.
"I joined the Academy at 15, not from a previous Academy but from playing Sunday League football. I used to row a couple of years before that, so to go from that to playing in front of a Millwall crowd is mental!
"I remember being on the bench for a FA Youth Cup game against Tottenham and also playing at Chelsea, and now to be here, it's a process in which I'm grateful for the opportunity."
