Manchester United start their pre-season this weekend with a home game against Championship side Derby County.
A huge number of the squad are yet to resume, as they are enjoying their holidays having played in the Euro 2020 tournament.
Solskjaer has welcomed his returning loan players and also the available players from the first team squad as well as the youngsters from the academy.
He has also urged the experienced players like Nemanja Matic, Juan Mata and Axel Tuanzebe to act as a guide for the young players.
Solskjaer said: “Well, pre-season is always a fresh start, a new start with new opportunities to look forward to the season.
“Some of the players have just started their holiday so we know it’s a depleted squad but it gives the young kids a taste of what it is like to have a proper pre-season with top professionals like Nemanja Matic, Juan Mata in the first team, Lee Grant, Tom Heaton is back.
“They’ve done it so many times. Mason, Aaron, Axel are first-team players who will bring these boys along and it’s a good opportunity for them.”
