Os Marialvas
Os Marialvas

Chaves host Os Marialvas in the Portugal Cup. Chaves have blown hot and cold over the last few months, mixing wins with some heavy defeats. Os Marialvas, meanwhile, started their season well but have cooled off sharply in recent weeks.

Os Marialvas have lost both of their appearances in this season's Taça de Portugal so far, without scoring in either game. That's the exact competition they now face Chaves in, so it's a pattern worth keeping an eye on.

Form check: two very different recent runs

Chaves' overall sample here is mixed, just nine wins from twenty games, with ten defeats and one draw. Look closer at the last five, though, and there's a livelier picture: back-to-back wins, including an away victory over Guarda in the Cup, sandwiched between a draw and a couple of losses. Chaves have shipped 33 goals across this run too, so defensively they've not been water-tight even during the recent up-tick.

Chaves: 20 completed matches; Os Marialvas: 20 completed matches.

Os Marialvas's overall numbers look considerably healthier: eleven wins, five draws and just four defeats from twenty games, with 31 goals scored against only 12 conceded. That's a tidy record on paper. The catch is timing: four of their last five matches have ended in defeat, including those two winless Cup outings already mentioned.

So this is a case where the bigger sample favours one side, and the recent snapshot favours neither.

How the tie could play out

Chaves get to play this one at home, which should help given how stretched Os Marialvas have looked over the last month. Most of Chaves' matches in this sample come from the Segunda Liga, while Os Marialvas's fixtures are largely from the Campeonato de Portugal, so there's a gap in the level of weekly opposition both sides are used to facing.

That gap doesn't guarantee anything in a cup tie, though. Os Marialvas have shown they can score goals in bunches, that 3-0 win over Fátima came only a few weeks ago, but they've also gone lifeless in defeats, netting nothing in three of their last five outings. Chaves will need to be sharper at the back than they have been recently if they want to avoid a repeat of one of those high-concession afternoons.

A cagey, low-scoring night wouldn't be a surprise if Os Marialvas dig in defensively rather than chase the game.

Put the two form lines together and neither side looks fully convincing right now. Chaves have the platform of home advantage and two wins on the bounce, but their season total still shows more defeats than wins. Os Marialvas have the better overall numbers but arrive having lost four of their last five, twice without scoring.

With that mixed picture and no market to weigh it against, we're happy to leave this one alone rather than force a pick.

Who will win?
