Kenny Jackett has been handed a fresh Pompey deal - after just 23 games in charge.
The former Wolves boss was appointed at the Fratton Park helm in June to replace Paul Cook.
And he has swiftly made a favourable impression on Michael Eisner to warrant a new contract.
Jackett has been rewarded with a two-year extension – taking him to the summer of 2021.
The 55-year-old had initially signed a deal until the summer of 2019, yet with Pompey 10th in League One, Tornante have moved to extend his stay.
In a club statement, chairman Michael Eisner said: ‘We have been really impressed with the experience, knowledge, hard work and commitment Kenny brings to Pompey and as part of our long-term strategy and thinking, see him as an integral part of our on-field future.
‘It was a simple decision for both parties to make.’
