Berkhamsted manager Mick Vipond wants his side to improve defensively despite Berko scoring eight times in their first two Spartan South Midlands fixtures of the season.
A 3-2 win at Hadley on Saturday was followed up by a 5-1 victory over Tring Athletic on Tuesday night but Vipond is more concerned about building from the back and keeping clean sheets.
He said: “We’re quite pleased but you don’t want to get carried away because you can’t always hope to score more goals than you concede.
“It’s very much about keeping clean sheets and, at the moment, we haven’t had one. This is a bit of a concern for me because that includes our pre-season friendlies as well.
“We’ve got some good attacking options with a mixture of youth and experience but we’ve got some good defensive players as well. It’s something we must address,” Vipond stated.
Josh Chamberlain equalised for Berko after Taylor Collins had put hosts Tring ahead, before goals from James Towell, Ed Canham, BJ Christie and Chamberlain again, sealed an emphatic win to send the Comrades top at this early stage.
Saturday sees Berkhamsted turn their attentions to the FA Cup extra preliminary round and Vipond is realistic ahead of a tricky away tie at Ashford.
“They play in a higher league than we do but it’s the FA Cup so we’ll aim for a bit of glory and you can earn a decent bit of money along the way for a club at our level,” explained Vipond.
“We’ll go there and try to get a result. If we can’t win we’ll try to get them back to our place. We look forward to it because the FA Cup is always a bit of an adventure for us and we’ll have go. A few of their players have played at a decent level so it’s going to be hard for us.”
