Benfica have taken 28 players to England for their preseason training camp at St. George's Park, home of the English national team. Victor Lindelöf, Jonas and Raúl Jiménez all return having been given extra time to recover from Euro 2016 and the Copa América.
Guillermo Celis, Andrija Živković and Reinildo are still awaiting visas to travel to the UK, but Benfica remain hopeful that they will be granted before the end of the week.
Marçal remains in Lisbon with a muscle strain, while Ederson continues to recover from knee surgery. Youth goalkeeper Miguel Santos drops out of the squad. Júlio César is unlikely to play but should be fit for the start of the season.
Sheffield Wednesday versus Benfica kicks off at 19:30 at Hillsborough on Wednesday night.
