Portsmouth found a physical Chichester side too strong as they suffered a 55-0 drubbing in London one south.
Coach Ian Chandler admitted his side were well beaten and struggled against the physicality of the home forwards.
‘The game was won and lost up front,’ said Chandler.
‘Chichester had a well-drilled, aggressive pack of forwards who bullied us out of the game.
‘We found ourselves up against an intimidating pack who dominated our forwards.
‘Only a few of our forwards were able to front up to them and it wasn’t enough.
‘It is something we have to get better at dealing with because their style of play seems the norm in our league.
‘Sides like us and Hove who play a more open, running style are suffering at the moment.
‘But we have to earn the right to impose our style and we didn’t do that.
‘Sometimes you have to do the ugly side before you can play your own rugby.’
In Hampshire one, Petersfield chalked up a third successive win beating Farnborough 44-27 at Penns Place.

Meanwhile, Fareham Heathens maintained their Hampshire two title bid with a narrow 3-0 derby triumph over Locks Heath Pumas.
