Guernsey coach Jordan Reynolds says his side must improve in the second half of the season if they are to stay in the hunt for the London One South title.
His side's failure to pick up a bonus point in their 19-0 win at Trojans has left him feeling frustrated.
"We need to hold the bar as high as we can," he told BBC Guernsey.
"Keeping it down to nil was fantastic for us but, at the same time, we had opportunities to score a couple more tries but we didn't finish those off."
Reynolds continued: "It is good that we got the win as it does put us into a really good spot.
"At the same time, if we're going to carry on playing these games and not picking up those four-try bonus points and finishing off tries when we have to, it's going to cause us a lot of grief at the end of the season."
