And it helped a smooth transition as the under-21s completed a winning week.
A late goal rush helped see off Everton 5-0 at Lancing in PL2 on Sunday.
That came less than a week after making the long trek to Burnley and enjoying a 2-0 success.
Shannon Ruth made four personnel changes to the XI and saw goals from Nehemiah Oriola (2), Shane Nti, Joe Belmont and Tyler Silsby see off the young Toffees.
Nti moved further forward as Harry Howell came into a No.10 role for the first hour and Solly March went on as sub at half-time.
Under-21s coach Ruth told The Argus: “What we saw today is probably what 21s football can look like.
“You’ve got a really experienced first-team player that obviously came from our academy coming down to get minutes.
“You've got a young player in Harry Howell who is in and around our first team coming down to get minutes before he goes away on international duty.
“Freddie Simmonds has spent a lot of time with the first team very recently.
“So the team today looked very different to the team did on Monday but what I was really pleased with was how together they were, which isn’t easy with all those changes.
“A lot of the information around the lads playing today would have come only yesterday or the day before.
“But we try and play with the same principles as Fabian and the transition of player between 21s and first team is so frequent, it means that when players drop down into play in a game, they look really together like they did today
“They played some really nice football and it gives us the best chance to perform as well as we can.”
Albion are at home to Aston Villa on Friday.
Simmonds and Howell have now departed on England under-18s duty.
