Midfielder Used To Play On The Holy Blues' Pitch"You have to get it in your head that it’s going to be a tough game but you have to be ready and make sure you get a result," said Lawrence.
"We have had a tough week training and it has been a good workout for the lads.
"The manager wants us to get rid of our inconsistency because we know we are better than some of the results we have had this season.
"We will be going all out for the win and I am very confident we can get it."
Lawrence is also confident the younger players in the Town squad will be ready for the atmosphere at the weekend.
"I felt that myself when I was at Mansfield and we played Burnley at home," he said.
"It was fantastic for me to test myself against higher opposition on that occasion and Gainsborough will be really excited to do that against us on Sunday."
Lawrence has been in the underdogs shoes before in his time at Mansfield, when they faced Burnley in the FA Cup in 2004.
"I used to live 20 minutes away from Gainsborough so I know them well," said Lawrence.
"I have played on their pitch plenty of times as a youngster.
"There is one main stand, and the seats were wooden when I was there so I don’t know if that has changed.
"The pitch is on a slight slope too! It will be a test for us because they will be well up for it."
“The fans of Gainsborough will be buzzing. A lot of my family come from there and they have all been asking for tickets and they have said the town is going mental.
"No one will be wanting us to win because everyone loves the underdog. The stand is very close to the pitch so it could be a bit intimidating for the lads.”
“The players there will want to put on a show and catch people’s eye so they will go for it and push us."
And Lawrence, who has ties with the area through his family, believes the Holy Blues' fans will be buzzing for the clash.
Town take on the National League North Side in The Emirates FA Cup First Round Proper at the Gainsborough Martin & Co Arena at the weekend (2pm kick-off).
