Granada would have been looking to return to winning ways against Barca on Saturday, having entered the contest off the back of a disappointing 2-0 loss at Eibar on January 3.
El Grana remain seventh in Spain's top flight, having picked up 24 points from their 17 matches, but the fact that they have already lost seven times this season is a concern for a team chasing a European finish.
The Red and Whites, who finished seventh in La Liga last term, have a busy period ahead as they will continue their Copa del Rey challenge against Malaga on January 15, while Martinez's team will take on Napoli in the knockout round of the Europa League towards the end of next month.
Osasuna, as mentioned, will enter Tuesday's contest off the back of a goalless draw with Real Madrid; it was a freezing night in Pamplona, and the home team managed to claim a welcome point.
Jagoba Arrasate's side are finding it difficult to escape the relegation zone at the moment, with a total of 15 points from 17 matches leaving them in 19th, one point behind 17th-placed Valencia.
Osasuna are unbeaten in their last four league matches, sharing the points with Elche, Alaves, Real Sociedad and Real Madrid since losing at home to Villarreal on December 19.
Los Rojillos have not collected all three points in La Liga since October 24, though, and they have lost their last two league fixtures with Granada by an aggregate score of 4-0.
Back-to-back draws with Sociedad and the reigning champions will hand them confidence, but a poor result on Tuesday would leave them in a difficult spot ahead of a huge game at Valencia on January 21.

Luis Milla is available, though, having recovered from coronavirus, and it would not be a surprise to see the 26-year-old return to the starting XI on Tuesday night.
Head coach Arrasate is expected to keep faith with the bulk of the side that picked up a point against Real Madrid, although there could be a start for Jony in an attacking position.
Granada possible starting lineup:
Silva; Foulquier, Duarte, Sanchez, Neva; Montoro, Milla, Herrera; Suarez, Soldado, Machis
Osasuna possible starting lineup:
Herrera; Vidal, D Garcia, Hernandez, Cruz; Oier, Moncayola; Torres, R Garcia, Jony; Calleri
We say: Granada 1-1 Osasuna
Osasuna have been the draw specialists in recent weeks, and we fancy the visitors to claim another point here. Granada have lost three of their last four in the league and will be wary of suffering another defeat, which could mean that Tuesday's match is a cagey affair.
