Chesterfield's Aaron Downes reckons new signing Barry Conlon could fire the Spireites into League One.
Manager John Sheridan drafted Conlon in on loan just hours before the recent home match against Torquay and the much-travelled striker grabbed the game's only goal.
Conlon joined Grimsby on loan from Bradford last March and banged in five goals in eight games to help the Mariners avoid relegation from League Two.
Downes was scratching his head when he arrived to see Conlon at Saltergate, but feels the 31-year-old will be a valuable asset as Sheridan's men aim to mount a promotion push.
"I was surprised to walk in and see him sitting next to me," Downes told skysports.com. "I said, 'what are you doing here? We don't play you for weeks!'
"I'd heard he was available and I knew it wouldn't take him long to find somewhere. He's been around a while and I'm sure a few managers would have liked him so I think we're quite lucky to get him.
"He's an impact player and hopefully he can make a big impact here and get a few goals, just like he did at Grimsby last season.
"He went there and kept them in the league, so hopefully this season he can do the opposite and put us up.
"We've not been scoring many goals lately so he's been a boost. He took his goal well and if he can keep doing a job for us then great."
