I see really good value on home side in this match up.

When I didn't saw odds on this game, I expect something around 1.50 on Sapporo, so currently lines are simply too good to skip.

Why I see Sapporo as so strong favorite in this game?

First of all, they plays in J1, one level above Kofu. Kofu is already 6 seasons outside J1. Sapporo is solid J1 team - two years ago they finished at 12th, previous season at 10th and currently they are on 11th place. Hosts are solid at home because they lost only once in current season at home - against strong Kashiwa (4th in league table). Kofu is 10th position in J2, but their form is not good. After 7 consecutive league matches without a win, in last round they finally recorded a win against Yamagata on away, but that was expected result - Yamagata had super hard schedule (third match in 6 days).

Sapporo here have good advantage in schedules - next match they will play at home against Gamba, so they don't have to travel anywhere. On the other hand Kofu played on away against Yamagata, now long trip to Sapporo and next long trip from Sapporo to Yamaguchi. Everything in short period of time, for sure it's challenging. On the other hand, I'm not sure Cup is their priority as they are not so far behind play off zone in league table.

On those circumstances I trust home team.

在这场比赛中，我认为主队的表现很有价值。

为什么我认为札幌在这场比赛中如此受欢迎?

首先，他们玩的是J1，比甲府高一个级别。甲府已经离开J1 6个赛季了。札幌是一支坚固的J1球队——两年前他们排名第12，前一个赛季排名第10，现在他们排名第11。东道主在主场很稳固，因为他们本赛季在主场只输过一次，对手是强大的柏大和(联赛排名第四)。kfu在J2排名第十，但是他们的状态并不好。在连续7场联赛无胜之后，上一轮他们终于在客场战胜了山形队，但这是意料之中的结果——山形队的赛程超级艰难(6天内的第三场比赛)。

札幌在赛程上有很好的优势——下一场他们将在主场对阵冈巴，所以他们不需要去任何地方。另一方面，甲府刚刚在客场对阵山形，紧接着下一个客场要到山口。所有的事情都要在短时间内完成，当然这很有挑战性。另一方面，我不确定杯赛是不是他们的首要任务，因为他们在联赛积分榜上并没有落后太多。

在这种情况下，我相信主队。
