It has taken him 25 games to get off the mark – with five of those coming during a spell north of the border as a teenager.
But the Pirelli Stadium on a cold night in November finally bore witness to Alex Robertson’s first goal in senior football.
The midfielder converted a Joe Rafferty cut-back to complete a fine passing move and wrap up a 2-0 victory for Pompey at Burton.
And Robertson was delighted to help the Blues return to winning ways after suffering a first league loss at the weekend.
The Australian said “It’s obviously nice to get my first professional goal and it’s a massive positive for us as a team to bounce back after the weekend.
“I thought I’d missed because their guy was stood in my way, but I’ve been looking for that cut-back for weeks.
“Raffs found me in the box and I just tried to guide the ball into the side of the goal where the keeper wasn’t positioned.
"There was a sense of relief and the gaffer has given me the licence to get into the box, despite playing in that deeper role."
“It was a really nice passage of play and so credit to him for finding me the way he did. Thankfully, I put it away.
“There was a sense of relief and the gaffer has given me the licence to get into the box, despite playing in that deeper role.
“Hopefully I can keep going now and score some more goals, but the main thing is that the team keeps getting results.
“I can’t do what I do on the pitch without the players and staff members around me – they provide me with massive confidence and belief.
“I think you’ve been able to see that when we do really get going, nobody can stop us. Now we need to see that from minute one to 90.”
Colby Bishop had earlier opened the scoring from the penalty spot, but was replaced at half-time with an ankle injury.
Robertson said: “I’m gutted for him. He’s been in fine form for us and is a great player, so hopefully it’s nothing too serious.”
