Nathan Thompson was brought off on the opening day of the season with a knee problem.
So the right-back was pleased to return to action as a second half substitute against Plymouth on Saturday.
He was the beneficiary of an injury on this occasion, with Anton Walkes not able to return following the interval.
It was the same story for Jack Whatmough, while Oli Hawkins limped from the pitch earlier in the contest.
And Thompson believes the fact that Pompey still managed to secure a 3-0 victory is a promising sign.
He said: “There were times last season when we lacked a bit of depth and that is what ultimately cost us towards the end.
“But the gaffer’s built a squad that can win promotion this season, with a lot of extremely capable players to choose from.
“I’m over the moon to be back. It’s difficult when you’re sat on the sidelines and the team are winning games.
"The gaffer’s built a squad capable of promotion this season, with a lot of extremely capable players to choose from."
“But you’ve got to be patient and also ready because you never know when your time is going to come.
“I had an injection to settle the knee down and that allowed me to strengthen it with no pain. Touch wood it stays like that.
“Anton has done fantastic for us so far, so I certainly can’t complain about having to wait to get back in.”
Ronan Curtis’ brace and a Jamal Lowe strike saw Pompey ease past Argyle to continue their unbeaten start to the League One campaign.
Thompson said: “The lads were fantastic, showing real confidence on the ball and dominating for long periods of the game.
“We had to make those enforced changes during the first half and at the break, but the team still looked solid.
“The likes of Carey and Lameiras were nullified when they came on and I thought it was a positive performance.”
