Colchester United travel to Devon on Saturday, to take on second placed Exeter City
The Grecians are level on points with Swindon Town at the top, and eight points ahead of seventh placed U's.
Matt Taylor's side were here at the JobServe Community Stadium less than four weeks ago, and an entertaining game ended with the points being shared after a 2-2 draw.
And McGreal is expecting the same again in Devon on Saturday afternoon.
He told the official website: "It was a great game here, and with the way the two sides want to play the game, I can see this one being as close and exciting."
"We're going there to win the game, and Matt won't be changing the way he wants his side to play and they'll want the points as well.
"That means we'll have to be right on our game again, and make sure we do everything right against them."
