JERMAINE McGlashan says he can afford to show former club Aldershot Town no sympathy as they visit Cheltenham Town.
The Shots have 15 matches left to save their Football League status, currently languishing in 23rd place, one off the bottom of the pile.
Winger McGlashan was handed his big chance at the EBB Stadium, joining them from Ashford Town (Middlesex) in 2010.
He thoroughly enjoyed his 18 months with Aldershot before leaving to join Cheltenham in a club record-equalling fee worth £50,000 just over a year ago.
McGlashan said he does not want to see Aldershot slip back out of the League, having won promotion as Conference champions in 2008.
But he knows Cheltenham must be ruthlessly merciless against them tomorrow if they are to maintain their hopes of an automatic promotion berth.
"It's not nice seeing how they are doing at the moment, but as long as it's after Saturday I hope they get out of trouble," McGlashan said.
"Unfortunately it won't get any better for them tomorrow.
"I have a love for that team as they were my first pro club, but we are going to be ruthless because we need three points.
"You want to play well against players you know as well and I am sure there will be some banter after the game, but during the 90 minutes I will be fully professional."
While he accepts his end product must improve, McGlashan is confident he has improved during his 13 months at Cheltenham, during which time has made 54 appearances and scored six goals.
"I feel I have matured since coming here and learned my trade," he said.
"I have changed my game and developed as a player.
"I will keep working on my end product and I also need to add more goals, but I am happy with the amount of starts I've made here and I am looking forward to continuing to develop."
Having experienced relocating west from the capital, McGlashan has done his best to help fellow Londoner Byron Harrison settle into his new surroundings, having arrived from Wimbledon in January.
"We used to talk about making it in the pro game when we were at Ashford together, but we didn't think we'd leave London and now we are both at Cheltenham," he said.
"It was hard for me when I first came and I have been trying to help him settle in because it's the business end of the season and it's important he feels happy here. I am looking to set him up on for a goal tomorrow if he is in the side too."
