Former U's midfielder on cup clash.
"Glenn is a very good manager, very calm and likes us to play the game in the right way. He has done really well and the icing on the cake this season would be promotion."
"Joe was my youth team manager and helped me after I signed my pro, so it'll be good to see him. I keep in contact with him, and still spend time with Woody, Hendo and John-Joe.
"This is a great game for me, I've still got some great friends at Colchester," he added.
The match will see Joe Dunne take his first FA Cup match as manager, with wily campaigner Glenn Pennyfather in the opposing dugouts and Sam knows that both bosses will have big parts to play this weekend.
"We can't wait, it'll be a big crowd and everyone at Chelmsford is looking forward to it."
Crossing his fingers that he'll get the nod for the weekend game, the U's youth team product told the official website: "When the draw was made, either Colchester or a lower non-league side would have been the best tie imaginable.
Sam, who returned to action for current club Chelmsford City on Tuesday night, is looking forward to the First Round Essex derby, which promises to be a cracking cup game.
Former U's midfielder Sam Corcoran can't wait to come up against his former team-mates and boss Joe Dunne in Saturday's FA Cup clash.
Ahead of Saturday, we asked Sam to tell us a bit more about his team-mates and here's what he had to say:-
He’s a good shot stopper and good with his feet for a goalkeeper. He likes to comes out for a lot of crosses, and is a pretty steady keeper.
Young keeper, who will be back up on the day.
An attacking full back, good on the ball. Richard's a young lad from Norwich City, who got released before being offered his pro deal and he's a very good player.
Another defender who is good going forward, but is strong defensively as well. Joined Chelmsford from Leyton Orient and has good experience.
A good ball playing centre half, very calm when under pressure and good in the air.
Kenny is the type of defender who wins everything in the air and he's a commanding centre half.
Centre half who has been around for a while. Very steady and reliable.
Left footed centre half, very strong and physical, played his first game on Tuesday and did well.
He likes to be on the ball and tries to make things happen for the team. He's on top of opposing players when they're in possession too.
Experienced midfielder who I'm sure Colchester fans know all about. Competes for every tackle, every header and is a great leader.
On loan to us from Dagenham, and he's good with his feet despite being a big lad, I'd say he's a Peter Crouch style of player.
A pure goalscorer, he's done it at every club and isn't afraid to shoot with either foot.
A box to box midfielder, very good in the air, scores goals for the team and has a good engine.
Quick left footed winger, very nippy, very tricky to play against.
Another player who is very quick, powerful and direct and puts in a good cross.
Ex-Southend, he's known as a striker, but sometimes plays out in left midfield for us, a very good finisher.
Donovan SimmondsVery quick striker, likes to get in behind and test his defender.
