Ben Thompson admits he has had to be patient but is now ready to make more frequent appearances after being given his first taste of Championship action.
The midfielder made 47 appearances for the club last season but had to wait until the visit of Burton Albion last weekend to make his Sky Bet Championship debut.
The early season form of Shaun Williams, as well as the summer arrivals of George Saville and Ryan Tunnicliffe has meant Thompson has had to bide his time playing for the U23s and making two appearances in the Carabao Cup.
"It's been a long wait but it was nice to finally make my debut in the division," Thompson told millwallfc.co.uk
"I have been on the bench quite a bit but I have been working hard in training and doing extras on my game and it has paid off.
"It was pleasing to get 30 or 35 minutes under my belt and I felt comfortable out there. I'll be ready again when my chance comes."
A knee injury to Shaun Williams has forced the manager to shuffle his squad recently and Thompson, who extended his contract with the club until 2021 earlier this year, hopes to be in contention for his first League start when the season resumes at Sunderland next weekend.
"It's going to be exciting," the 22-year-old added.
"The club hasn't played there for a while and it's a great stadium to go and play football. I have watched plenty of games there on tv and they have some very good players.
"We have had some good results against the big teams in this division and i'm sure we can take a lot of confidence from that when we head up to Sunderland after the international break.
"It's going to be a good experience for us."
