Sagan Tosu are in a bit of an odd spot to start the season.

As expected, an excellent defense has showed up but their attack has managed just three goals from four matches. They are undefeated to start the season, but with three draws and only one win, their six points has them in sixth place.

So how good are Sagan? We’ll get a good idea this weekend.

Kenta Kawai’s men travel to Yokohama for a battle with F·Marinos. Sagan’s great defense will be tested by Teruhito Nakagawa and Takuma Nishimura, who are both off to great starts this season, as well as the always-dangerous Anderson Lopes. Meanwhile the Sagan attack will have to break through against a Marinos defense that is beginning to find its footing and has Eduardo, the standout centerback who starred in Tosu a year ago.

Simply put, a lot will be asked of Sagan Tosu and we will have a good idea whether they are the team who are undefeated or the team struggling to get wins.

Marinos, on the other hand, are right where they expected - challenging Kawasaki Frontale at the top of the table. If they are to unseat the champions, they will have to get every point available to them all season long. Their two biggest additions, Anderson Lopes and Eduardo, have yet to really shine yet, but they are still churning out enough points to stay in the race. A win over Sagan will go a long way to setting them on that track and keeping up the title challenge.

Will things go the way of Sagan and another strong season in Tosu? Or will Marinos have the edge and heat up the title race further? We’ll find out in Yokohama to kick off Matchweek 5!
