The 27-year-old scored his second brace of the season in a 2-1 victory at Lincoln on Saturday to bring his remarkable tally up to seven.
Speaking to the Buckinghamshire Advertiser, Sandell said: "If I can get double figures than that will be great.
"I got five last year so I have beaten that and I have a few more games to get 10.
"There are not many full-backs who can do that so it would be a good achievement.
"I have been thinking that I have been due a goal for about 10 games but it just wasn't happening for me. I'm happy with the goals and the three points."
