Pompey are likely to ring the changes for Tuesday night’s Papa John’s Trophy clash with Crystal Palace’s under-21 side.
A mixture of youth and experience will be on display at Fratton Park for the final contest in Southern Group B.
Both sides can qualify for the knockout stages, although the Blues also need AFC Wimbledon to lose at Sutton and for there to be a swing in goal difference.
And Michael Jacobs is hoping to get a chance to impress having been on the periphery in recent weeks.
The midfielder said: “It will be a good opportunity for the lads who haven’t been playing regularly to get some minutes.
“And the young boys will get the experience of being around the first team and appearing at Fratton Park.
"Those guys who are on the pitch on Tuesday need to do well in order to push the ones who have been in the team lately."
“There should be a good blend and hopefully we can get a positive result because the first two games didn’t go as well as they could have.
“We’ve still got a chance of getting through to the next stage, so we have to produce a positive performance.
“Those guys who are on the pitch on Tuesday need to do well in order to push the ones who have been in the team lately.”
Pompey face a young Eagles outfit who are playing in the competition for the first time and beat AFC Wimbledon in their last outing.
Jacobs said: “We saw a bit of Crystal Palace at St George’s Park over the summer and the new manager will have his philosophy that will be shared across all the teams.
“I’m sure they’ll be a possession-based side and will like to pass the ball around. It will be a good test for us.”
