Mingueza re-joins first-team training on Monday after missing the Como Cup outings, as the Eagles continue to build towards the start of the new Premier League season.
The 27-year-old Spain international became the first recruit of the Sage-era when joining from Celta Vigo last month.
During the pre-season trip to Italy, Sage sat down for an exclusive interview with Palace TV and was asked what he thinks the summer recruit can bring to the group.
"He will come back on Monday, as will [midfielder] Adam Wharton, that will give us more solutions," Sage said.
"What is interesting with Oscar is that he's able to play on both the right and left. He has both the quality and this versatility.
