Will Knight is backing Havant to complete a London one south double over relegation-threatened Twickenham.
The Hooks Lane outfit stormed to a 42-15 home win earlier in the season and the head coach wants more of the same in west London.
‘We had a definite edge over them up front,’ said Knight.
‘That enabled us to play our expansive game of 15-man rugby which proved far too good for them on the day.
‘Although we have had a few changes in personnel since then, we must be looking to pick up another win.
‘In this league any team is capable of causing an upset so we have to approach the game in the right manner.
‘If our forwards get on top again then we have to make sure we exploit that advantage.’
The visitors are waiting on the fitness of experienced back-row forward Steve Cruddas.
But Mike Brook is definitely absent because of work commitments.
That means second-team prospect Christian Roberts gets another opportunity to stake his claim.
He appeared in the recent Hampshire Cup victory over Basingstoke but now gets his chance to taste league action.
In the three-quarters, Havant are boosted by the return of powerful runners James Reed and Ben Brierley.
Outside half – and captain – Joel Knight is still a little way away from returning after breaking his hand.
Havant comfortably sit sixth in the table, with little prospect of promotion or relegation.
The head coach, however, feels his team still have plenty to play for.
‘We don’t intend to let the season drift away in the closing stages,’ added coach Knight.
‘Our aim is to consolidate where we are and push higher if we can.
‘Between now and the end of the season what we do is important towards preparing for next year.
‘The next season is a big one because of the planned re-organisation of the leagues.
‘It is a case of finding the right balance and giving players opportunities to help their development.
‘We want to make sure we build on the progress we feel we have made this season.’
