Millwall boss Neil Harris believes Jed Wallace has "all the attributes to be a top player" after the winger signed a new long-term contract on Thursday afternoon.
Speaking to millwallfc.co.uk after Wallace put pen-to-paper, the manager described the deal as a "big statement" by the club, and also lauded the winger's "outstanding" work ethic.
"Since Jed came to the club last year, and before that on loan, his performances have been outstanding," said Harris. "We have to remember he's still a very young man in footballing terms. He's played quite a lot of football and has Football League experience.
"His end product is improving all the time, his work ethic has been outstanding and he was a big part of what we achieved last year in stabilising ourselves in this division. There was a lot of speculation and interest in him over the summer, which was no surprise for us.
"The fact he wanted to be here, the fact he's committed his long-term future to us, he's the sort of player we want to work with. We want to build our football club around young and hungry players, but with some experience as well. Jed committing his future to the club is a big statement by the club.
"To put our faith and trust in a young player, it's pleasing for me as a manager to see the club moving forward in tying down our youngsters."
Wallace has re-joined the club three times, initially on loan in January 2016, before signing temporarily again 12 months later and securing a permanent transfer in the summer of 2017.
Interest in the winger was no secret in the close season, but the manager spoke of his pleasure in keeping Wallace - and stated that there is "so much more" to come from him.
"We took him on loan from Wolves and he was a good fit from day one. We enabled him to express himself and to play with good pace, freedom and excitement, as well as giving him a structure. All young players need that opportunity to express themselves and be that maverick sort of player, but they need structure and organisation.
"Jed fits into our boundaries perfectly. He then came in permanently last summer, with him joining George [Saville] and young Jake [Cooper]. Three bits of good business, we felt there was a lot of value in those players. We got them extremely cheaply, and we've seen George move on for big money to Middlesbrough, whilst interest in Jed was at the forefront during the transfer window.
"We managed to keep him, he wants to be here, and I can see Jed continuing to grow as a player. There's so much more to come from him. He's got all the attributes to be a top player."
