‘It was one heck of a game, with both teams putting 100 per cent into it, even though there was nothing resting on it.
‘No-one on either side shirked any tackles or any contact – it was a good, hard -fought game of rugby and a good win for us.
‘We’ve pulled away from Bognor a bit which is good and caught up a bit on Twickenham.
‘It was a fantastic day with a big crowd, which helped us a lot and lifted the players.
‘There has been a little bit of criticism around the club that the players have perhaps not shown the passion they should.
‘The performance of the players showed it is not justified.
‘There was nothing at stake but it was a great game, with Twickenham playing fantastically well also.
‘For both teams to fight and work like that shows just how hard and tight this league is.
‘There were times when, if either team had relaxed, they could have been on the wrong end of a heavy score.’
