'Barney' took just 16 minutes to make his mark with the opening goal as the Railwaymen beat Huddersfield 2-0 in League One on Saturday.
Our reserve top scorer in 2004-05 and 2005-06 is on loan at Crewe until January.
Technical director Gradi said: "The new boy made a big difference, especially in the first half. As soon as he got in with that ball and cut across his opponent I had no doubt he was going to score. He's a good player and he gave us more of a presence than we've had for a while."
Dario Gradi was full of praise for Lee Barnard after the striker marked his debut on loan to Crewe with a goal.
