The striker put in an impressive performance in the 1-0 win over Falkirk at the Rock, which culminated in him firing into the top corner from 20 yards which nine minutes to go.

Campbell hadn’t started a match since February’s trip to Easter Road, he has instead been forced to make his contributions from the bench. Murray believes Campbell’s attitude has shown the way for other squad members who have been on the fringes at Dumbarton, having played his way into the manager’s plans for Saturday’s trip to Cowdenbeath.

Murray said: “Archie has been flying in training, that’s why we played him, he has shown an appetite which is great. Hopefully that endears him to other guys who aren’t playing as much as they want.

“He has shown a great attitude and as I say he is scoring goals for fun in training so we thought we’d put him, he caused Falkirk problems the last time we played them.

“He has played himself into the team now, because I had a team in my head for Cowdenbeath and it has probably changed a bit now.” The Sons boss praised his side for sticking to the gameplan he set them before the tie. With Sons playing into a strong wind in the first half conditions were difficult but Murray thought his team coped well.

He added: “We knew the wind would cause big problems for both teams. We played 4-2-3-1 in the first half and asked the guys to get us in level at half-time as a minimum and then we went 4-4-2 in the second half and tried to win the game.

“At the end of the day it is a wonder strike that has won the game but I thought the guys showed tremendous discipline to handle the gameplan and handle Falkirk to restrict them to minimal chances.”
