In this match we are dealing with two highly defensive teams. With the restart, Thun in 5 matches has scored 4 times while her home has been violated only 3. Lausanne in 4 matches has not yet managed to score while she has conceded only one goal.
This is due to the way they approach the games since their first concern is to secure the zero and then that it comes out ahead. It is characteristic that in all their matches they create few opportunities since there is no creativity in the attack.
With these data I believe that the 1.80 that exists for under 2.5 is big and worth a bet.
