Portsmouth are running out of time in London one south.
The Rugby Camp outfit need to show a major improvement on home turf against Sidcup tomorrow if they are to boost their ailing survival hopes (3pm).
Ian Chandler’s men stayed in the bottom three after their disappointing 36-31 home defeat by Beckenham.
And they cannot afford a repeat performance tomorrow.
The home side were their own worst enemy last weekend, missing crucial tackles as they lost a game they could – and should – have won.
‘We have been working on our defence all week and I am not expecting us to make the same mistakes,’ said coach Chandler.
‘The reason we didn’t win was because of our own lapses.
‘We didn’t tackle and made some wrong decisions.
‘Our defensive record is the second worst in the league and that tells a story.
‘It is important we remain at this level, otherwise we will be in danger of falling behind other local clubs in the pecking order.
‘With Havant and Gosport & Fareham coming into this league next season, we want to be with them.’
Already without up to seven first-team regulars through injury, Portsmouth suffered further blows during the week.
Ace finisher Matt Gronow is ruled out by a neck injury and forward Luke Richardson has a broken hand.
The home side does, however, welcome back outside-half Dan Neville.
‘Sidcup have a good set of forwards, including a very useful number eight,’ said Chandler.
‘We know what to expect and it will be up to the players to execute our plan.
‘In times of adversity you look for the spirit and character to get you through.’
