The hosts kick off their Championship campaign next Saturday following a pre-season trip to Austria, while the visitors head to Osasuna for their La Liga curtain-raiser in mid-August following last season's promotion.
Match preview
Sheffield Wednesday return to Hillsborough on Saturday a week before raising the curtain on their second consecutive Championship campaign in search of a second victory of their pre-season preparations.
The Owls looked set to be preparing for another League One promotion bid in the 2024-25 term, having sat in the relegation zone of England's second tier for almost the entirety of last season, only to steer clear of the drop in eye-catching fashion under Danny Rohl's tutelage, going unbeaten in their final six outings, including three straight victories to end the season, to finish 20th on 53 points, three above the bottom three.
The South Yorkshire outfit then began their preparations for the new campaign with a trip to sixth-tier Alfreton Town in early July, picking up a 2-0 victory thanks to goals from Josh Windass and Mallik Wilks, before travelling to Austria and suffering a 4-0 beating at the hands of 17-time domestic champions Red Bull Salzburg.
Rohl's men concluded that trip with a contest against German side Werder Bremen last Friday and played out a creditable 2-2 draw in Tyrol, coming from 2-0 down in the second half thanks to goals from Anthony Musaba and Djeidi Gassama.
Now heading into their final pre-season test before kicking off their new Championship term at home to Plymouth Argyle next Saturday with the aim of putting a stronger campaign together, Sheffield Wednesday will be keen to bow out with a home win to build confidence following a busy summer of arrivals.
Their visitors, meanwhile, also enter a final outing of their pre-season run in preparation for their return to La Liga in the upcoming 2024-25 term.
Following their relegation from Spain's top flight in 2020 and a pair of disappointing second-tier finishes, Leganes punched their ticket back into La Liga last time around by topping the Segunda Division, collecting 74 points from their 42 outings having leapfrogged previous leaders Real Valladolid with a final-day victory.
They returned to action in a trip to France to meet Nice in mid-July and played out a 2-2 draw thanks to goals from Diego Garcia and Roberto Lopez, before most recently taking on Alcorcon last week and suffering a disappointing 2-1 defeat, having initially fallen two goals behind before Seydouba Cisse halved the deficit from the penalty spot nine minutes from time.
Now travelling to South Yorkshire for their final scheduled friendly, Leganes will be keen to put a win on the board before returning to top-flight action later this month.
