Chopper excited to be coming up against "true gent" TeddyMillwall manager Neil Harris is expecting Teddy Sheringham's Stevenage side to provide The Lions with a different type of test to what they have experienced so far this pre-season.
Harris famously overtook Sheringham's goalscoring record during his second spell as a player at The Den to become the club's all-time leading marksman.
The duo are both approaching the start of their first seasons as full-time managers and Harris is looking forward to sharing the touchline with a fellow prolific former Lions striker this Saturday at The Lamex Stadium.
"It was a privilege and a proud moment when I took Teddy's goalscoring record," the boss said.
"He sent me a lovely message afterwards so that goes to show what a true gent he is within football.
"Like myself, though he is a little bit older than me, he has his first managerial chance so we wish him all the best for the season.
"It will be a good test for both of us. They will be a different style of opposition to what we have played.
"Teddy's team will play a lot of football, they will pass out from the back and we will come up against teams in League One who do the same."
Lions trio Paris Cowan-Hall, Lee Martin and Lee Gregory could all get their first outings of pre-season against The Boro.
"Paris has been training and he is progressing," Harris said.
"He has had a couple of weeks as a set-back and he is really keen to impress and get back going and firing.
"Both Lee's have had a week without a fixture but the boys have worked extremely hard so a week isn't the end of the world.
"Lee Martin is back in training and will be good to go on Saturday and Lee Gregory is the same."
