The race for promotion from League One is set to go right down to the wire.
All of the top four sides – Luton, Barnsley, Sunderland and, of course, Pompey – won their opening fixtures of the Easter programme.
Matt Clarke grabbed a dramatic stoppage-time winner as the latter were victorious at Burton on Good Friday.
Now Pompey require a similar outcome against Coventry and Kenny Jackett knows the Fratton faithful will play their part.
The Blues boss said: “Performances have been good lately and if the fans see another one on Monday then I’m sure they’ll get behind us.
“They were excellent at Burton on Friday – as they have been throughout the season – and are a real asset to this club.
"To have the points total we’ve got and still be in fourth position just shows the quality of this league."
“It’s a tight turnaround, but it’s the same for both sides and we have a good squad, so I’m confident that people could step in if required.
“We’re keeping the pressure on Luton and Barnsley – to have the points total we’ve got and still be in fourth position just shows the quality of this league.”
Pompey’s opponents appear likely to miss out on a top-six finish, despite losing just one of their past seven games.
Jackett said: “It’s probably frustrating for them because despite the run they’ve had, the sides above them have also kept winning.
“That means they haven’t been able to make their late dash really pay to get into those play-off places.
“But it’s their first year up in League One and I’m sure they’ll be aiming to be in a similar place to us next season.
“We’ve gone a bit better after finishing eighth last time to get into a good position that we want to capitalise on and Coventry are also a very big club.”
Pompey will welcome back former Fratton favourite Conor Chaplin, who joined the Sky Blues last summer.
Jackett said: “Players go back to their old clubs all of the time, but I’ve got a lot of time for him and he’s a smashing lad.
“Hopefully things don’t go well for him on Monday because we’re trying to win, although I’m sure everyone in Portsmouth wishes him well.”
