Alex Robertson has adapted quickly to senior football since his summer loan switch from Manchester City.
His only previous experience of the first team game was a handful of appearances during a short stint with Ross County a couple of years ago and two caps for Australia.
But the 20-year-old is currently enjoying a run of matches in a Pompey side that are sitting top of the League One table.
And ahead of Saturday’s trip to Wigan, he is determined to keep learning and improving during his stint on the south coast.
Robertson said: “It’s been enjoyable and we’ve started the season off strongly as a team – hopefully we can keep that going.
“We work hard every day and to see that taken onto the pitch to get results is fantastic, but now we want to stay top.
“This is very new to me because it’s one game a week at under-23s level and it’s all been pretty hectic here.
"The intensity is quick and I’m still learning every day and with every game that I play. It’s crazy when you’re out there in front of so many Pompey supporters."
“But the body’s feeling alright and I’m looking forward to Wigan this weekend. The main thing is that I’m getting the exposure and more experience.
“The intensity is quick and I’m still learning every day and with every game that I play. It’s crazy when you’re out there in front of so many Pompey supporters.
“I came into this loan with an open mind and the gaffer’s been great, as have the staff and all the boys.
“I love it here – the weather’s certainly different down south than it is in Manchester! The whole environment is great.”
Robertson has already collected six bookings, with four yellow cards in the league meaning he is one away from a suspension.
He said: “It’s more learning for me because they’ve been stupid little things. I think I only had one for a tackle.
“The other cards are for things that referees are clamping down on more, so I’ve just got to keep my mouth shut and be a bit smarter.
“But I play with a lot of passion when I’m out on the pitch and just want to do well for myself, the team and the club.”
