Internacional against Corinthians looks like two bad form strings meeting (LWLLD and LLLLL in the table data), but the match records say the two sides are losing in opposite ways. Corinthians have out-shot every visitor they hosted this stretch and still lost all three. Internacional won their one recent away game from just 4 shots. After roughly 17 days without a league game for both, I'd watch which of those habits survives the break.
The numbers, all from our match records. Corinthians at home: against Chapecoense, 16 shots to 7 and xG 2.12 to 0.95, lost 1-2 after scoring in the 2nd minute and conceding in the 40th and 77th. Against Santos, 18 shots to 8, only 2 of them on target, lost 0-1 to a goal in the 33rd. Against Fluminense, 20 shots to 10 and xG 2.44 to 2.38, lost 1-3, conceding in the 24th, 76th and 93rd. So the pattern is not that they never create chances. It is that the game tends to tip after the 75th minute, and in two of the three it did.
Internacional are the mirror image in some ways. Their 2-1 win at Chapecoense came with 4 shots to 13 and xG 0.34 to 0.70, goals in the 25th and 67th. The home game against Santos went the other way: 0-3 down at the break, with a red card in the 28th minute, then 2-3 at the end with xG almost level (1.29 to 1.36). And against Atletico-MG they had 23 shots, 11 of them blocked and 3 on target, for a 0-0. The list of absences also has goalkeeper Rochet out (lower back), so I'd be careful about reading too much into their old defensive numbers.
Where it gets interesting is the head-to-head. In the cup earlier this season Internacional won 2-0 at home and lost 1-2 away, and in the league Corinthians were beaten 0-1 in April. None of that tells us much about the current shape of either team, but it does show that a one-goal margin is the normal size of this fixture.
My honest read is that this is a match about who scores first and how the late stretch is managed, not about who is "in form". If someone follows these two closely, I'd like to hear whether the late concessions at Corinthians look more like fitness or more like bench choices.
