Player coach Dave Wheaton admitted his side had problems before the start.
He said: ‘We travelled with a new-look squad and only 16 players due to late cry offs.
‘But I cannot fault the effort put in by the lads.
‘I asked for want and effort and that’s exactly what was delivered but on field injuries and a concussion depleted our numbers still further.
‘Matters got worse when we were forced to go to uncontested scrums with our numbers reduced to 12.
‘When it’s tough the true character of a player reveals itself, and I was very pleased with how the players dug deep and never gave in.
‘Bognor away is a very tough encounter but for the most part we were able to hold the Bognor pack.
‘It was when the injuries came that more gaps appeared in our defence and their powerful forwards began to score.’

‘Our play in the loose was fantastic particularly in the backs.
‘We were able to move the ball out wide and cause their defence all sorts of problems.
‘Also or support play was good and the main reason we were able to finish off so many of our moves.
‘At the same time we were dominant at the set-piece giving us the platform to play from.’
