The Canada international is working his way back to full match fitness after returning from a leg break suffered towards the end of last season.
After featuring in victory over Como, Buchanan told DAZN: "We started working last year, I'm improving game by game.
"This year I hope to make the leap in quality.
"The process is going well, I'm increasing my minutes and I feel improved in these last few weeks."
