Darlington boss Mark Cooper has praised debutant centre-back Exodus Geohaghon following his performance in Tuesday's 4-3 win against Stockport County.
The 26-year-old completed a month-long move to the Blue Square Bet Premier club on the day of the game.
"I've had him before, Kettering, and Peterborough in the Championship, he's not a mug," Cooper told BBC Tees.
"He stuck his head on some balls, he got us out of a few scrapes with his big size-12s, he's a good centre-back."
Cooper added: "Also he's got that long throw that we can do some work on and get some benefit from it."
Geohaghon was signed by League Two side Barnet in August following a spell at Peterborough, making three appearances before joining Darlington.
Meanwhile the Quakers boss was also impressed by the efforts of midfielder Jamie Chandler, who replaced the absent Ian Miller as captain.
The 22-year-old, who joined from Sunderland in the summer of 2010, scored twice from midfield to open his account for the season.
"I was a goalscoring midfielder and I've been crying out for someone to get on the end of things inside the box," Cooper continued.
"I'm working on him, telling that he has to make sure he lands on things that bounce on the edge of the box, and sometimes they come off the keeper and you get a tap-in.
"You get your rewards if you keep getting forward and tonight, he's added that to his game and if he keeps adding that to his game then becoming a not bad little midfield player.
