Kenny Jackett has praised Gareth Evans, who could make his 200th Pompey appearance at AFC Wimbledon on Saturday.
The midfielder has achieved a lot on the south coast since initially arriving for a trial in the summer of 2015.
He scored in the games that secured both promotion from League Two and the title, also netting in the shoot-out success over Sunderland at Wembley last term.
But Jackett believes that Evans still has plenty more to offer the club in the weeks, months and years ahead.
The Blues boss said: “It’s a fine achievement – there aren’t many who reach that number and he deserves it.
“He’s been a fantastic servant for this club and although he’s into his 30s now, shows no signs of letting up.
"The qualities he has really enhance the team and I’m sure there will be many more appearances to come from him."
“Gareth is one of the fittest players in this squad, although his days in the wide areas are now probably being replaced by coming inside slightly.
“The qualities he has really enhance the team and I’m sure there will be many more appearances to come from him.
“He makes training and competing look easy a lot of the time because of his fitness levels and enthusiasm.
“That’s why he’s such a popular member of our squad and he’s someone who will never let you down.”
Pompey are unbeaten in three league games, but are looking for a return to winning ways when they visit AFC Wimbledon on Saturday.
Jackett said: “We didn’t capitalise on our chances enough against Gillingham last week and that’s something we need to improve on.
“Drawing was a frustrating outcome and we fell away a bit, so are looking for a better outcome on Saturday.
“Wimbledon are on a good run at the moment and they have threats going forward, which will require us to be at our best defensively.
“They’re capable of creating a lot of opportunities, but I know there’s a win there for us if we get our own game right.”
