Town head into the weekend’s action after a run of three straight defeats that has seen the side slide to within three points of the bottom two.
Conversely, the Dons are flying high in third and have lost just once in their last seven outings to remain in the automatic promotion spots.
However, determined to get back to winning ways in Milton Keynes, Gafaiti told iFollow Glovers: “We know that it’s tough but we’re working and that’s the only thing we can do at the moment. There’s no other option for us.
“We know it’s a bit complicated but what we’ve got to do is work. Everyone is working hard, everyone is focused, everyone knows that we only have one objective which is to pick up points and that’s what we want to do.
“If they have good attackers then we have to make sure we defend well. We’re going to be ready for it.
“They can be the third best attackers in the league but they can be sure that we will come there and be ready for them and they will have a very, very hard challenge.”
The reverse fixture ended in a 1-1 draw at Huish Park with loanee Olufela Olomola netting a late equaliser for Darren Way’s side.
Having recently suffered a narrow 1-0 defeat at table-topping Lincoln City, Town’s defender revealed confidence remains high despite the perilous league position.
“For the players, the staff and all of us involved at the club but I think everyone knows what we have to do and this is why we’re here.
“Of course we have pressure, we can’t lie about it but pressure is part of football. Sometimes you have pressure to win a title and sometimes you have pressure to avoid relegation.
“We are in the spot where we know the situation is a bit tough but we still have three points above the bottom two teams and we’re confident. We keep training hard, keep helping each other at the training ground and this is how we’re going to make it.”
