Cheltenham manager Mark Yates insists his team still have a lot of work to do to reach the League Two play-off final.
Goals from Jermaine McGlashan and Ben Burgess handed the Robins a 2-0 advantage in the first leg of the semi-final but Yates believes the tie is far from over.
He said: "We are at half-time and are 2-0 up. It is far from over but if we play with the same attitude and quality on Thursday then we will give ourselves a chance.
"I am really pleased with the clean sheet. There were a couple of back post headers that we should have dealt with better but I'm not going to complain as the players have put another good shift in.
"We put Ben [Burgess] in to give us something different and he has certainly done that. He has added a different dimension to our play. But although we have two big strong forwards, some of the football we played was decent."
