The boss explained on Wednesday evening that Jones will be a part of the first-team centre-back group alongside incoming French defender Raphael Varane.
He also stated that the signing of Varane – which the club announced on Tuesday subject to the completion of personal terms and a medical – is likely to lead to a loan move for Axel Tuanzebe, who played well in United's exciting 2-2 friendly draw against Brentford.
“Of course, with Raphael coming in, I can see Axel going out [on loan], because I have Varane, Maguire, Lindelof and Eric Bailly and Phil Jones is coming back in,” Solskjaer said.
