Holgate featured at right back on his league debut for Albion, as they conceded late against Norwich City after holding a one-goal lead for much of the game.
The Everton loanee was impressive throughout, providing the cross for Dwight Gayle to give the Baggies a 12th minute lead.
The 22-year-old, who has played nearly 50 times for Everton, believes Albion have what it takes to bounce back to the big time, and he joined the club to be part of a promotion push.
He said: “You can see in the squad we have enough in their to close the gap, it is a Premier League squad.
“We were aiming to win the Norwich game, and I think it is credit to the lads that we believe we can go out and beat the second placed side comfortably.
“We were disappointed not to get all three points, but it shows what we have here.
“The gaffer was one of the reasons I came here, and the other was promotion.
“I, and a lot of other people, believe we can get that and I wanted to be a part of it.”
Throughout the Norwich game Holgate, who can also play at centre back, was a constant threat to the Canaries, providing numerous dangerous crosses.
He has described the three-pronged attack of Gayle, Jay Rodriguez and Hal Robson-Kanu as a dream for him, and he hopes he can provide more assists as the season goes on.
He said: “The front three are always going to be in the right areas, and they are a dream for me.
“You know someone is always going to be there, so I just need to put it in the right area.”
Just days after Holgate arrived through the doors, another impressive loanee Harvey Barnes has gone the other way, being recalled by his parent club Leicester City.
Holgate has admitted the players were gutted to lose one of their star performers.
But he has backed the others in the squad to step in to fill the void left by the Foxes flair player.
And Holgate also reserved praise for the pool of young talent Albion have at their disposal, including Rekeem Harper, who impressed on his full debut in the draw with Norwich.
He added: “It was disappointing to lose Harvey as it is clear what he has done for us here, I only got to know him for a week and he was a nice guy.
“It is going to affect us, but we are good enough to move on from that and be just as much of a threat as we were with him.
“The young lads have been massively impressive, the training sessions I have seen they have been good.
“A few of them played in my debut against Wigan last week.
“There is a lot of talent coming through and it is going to be a good time over the next couple of years when they can get game time.
“I think it is good for the future with the likes of Rekeem, Sam (Field) and Jon (Leko), it is a good group of good players.”
