Dumbarton manager Jim Duffy was again left frustrated at the weekend as his side shot themselves in the foot to draw with Montrose.

Trialist Boris Melingui had Sons on course for all three points, but Martin Rennie converted a penalty in the final minute to grab a point for the Gable Endies.

Duffy felt the spot kick was a situation his side should have dealt with.

He said: “We’re extremely disappointed that we end up losing a cheap goal again. We just seem to take it in turns almost of making an error.

“It was a difficult game. Montrose were the better side in the first-half. We struggled to cope with their shape.

“There’s only about six minutes to go so that’s when you’ve got to be resilient and fully concentrated and unfortunately it was a little bit of a mix-up that caused the penalty and you’re then going from three points to one point.

“There was some decent aspects of the play today and we got better as the game wore on but a lapse in concentration has cost us.

“There’s still a lot to work on and we’re disappointed not to hold on and get all three points.”

Duffy has already strengthened his side during the January window with the loan arrivals of Ben Armour, David Ferguson and Henk van Schaik.

All three started on Saturday with Ferguson and Van Schaik, who joined on loan from Ayr United and Livingston respectively, partnering each other at centre-back.

The Sons boss admits it might take time for the partnership to come good, but praised the duo for stepping in confidently.

He added: “They’re two young guys but we felt we needed to strengthen in that area with Andy Dowie leaving, and injuries over the last wee period.

“We can’t arrange reserve games because we don’t have the resources to do that so sometimes it takes players longer to get to match fitness.

“There were some good things but a lapse in concentration has cost us.”
