Option D is the correct answer. 

In the first blank, we need to use the past perfect tense( had already finished) . The past perfect tense describes an action that was completed before another action in the past. In the given sentence, the football match finished before the speakers arrived. This means the action of the match finishing occurred earlier in the past than the action of their arrival. Therefore, "had already finished" is the appropriate form to use here.

In the second blank, we need to use the Simple Past Tense (arrived). The simple past tense describes an action that occurred at a specific point in the past. "Arrived" indicates the time when the speakers reached their destination (in the past), which is a later event compared to the match finishing. Therefore, the simple past form "arrived" is the correct form.

The other options are not grammatically correct.
