Joe Morrell has produced some impressive performances for Pompey over the past few weeks.
And the summer signing insists that he has even more to offer the side as the 2021/22 season progresses.
The midfielder admitted that it took him a little bit of time to settle after making the switch from Luton.
But now, with a tricky trip to Rotherham up next for the Blues this weekend, he is aiming to make further strides.
Morrell said: “I don’t want to stand here and say that this is all I’ve got because I’m not someone who will ever be content with what I’m giving.
“I’m always going to be quite hard on myself and pushing for more, while it was always going to take time because I didn’t really have a pre-season.
“Plus I caught Covid and it took a while to get back from that, but I’m the sort of person who wanted everything yesterday.
"I don’t want to stand here and say that this is all I’ve got because I’m not someone who will ever be content with what I’m giving."
“There were conversations with the gaffer and Nicky, with them saying it wouldn’t come straight away – and they were proved right.
“I said after the Wigan game that there was more to come from me and I think you’ve seen that, but there’s still more I can give.
“We’ve got a tough schedule coming up, with the likes of Rotherham and Ipswich to come – two sides everyone expects to be near the top of the league.
“But I want to contribute in all aspects of the game and have tried to show that, looking for a platform to drive forward with the ball and offer more in the attacking phase.”
Morrell has recently returned from international duty, helping Wales draw with the Czech Republic and beat Estonia in World Cup qualifiers.
He said: “It’s always something that’s very enjoyable for me and I take great pride in representing them.
“We were a bit disappointed not to win the first game and it leaves us with a bit to do next month – we’ll probably have to get a point off Belgium.
"That’s obviously not going to be easy, but we’ll give it our best shot and I think we deserve to finish in the top two.”
