The English midfielder had a spectacular loan spell with Hammers last season.
Lingard sealed a loan move to West Ham in the final half of the last season after running out of game time under Solskjaer.
As it turned out, the 28-year-old had an impressive loan spell, steering David Moyes’ side to a sixth-place finish, meaning they will play in Europa League next season.
It was the best version of Lingard over the years after he notched up 9 goals and 4 assists in 16 Premier League appearances.
Now, Solskjaer has ensured that the English attacking midfielder will be part of his plans going into the next season.
Solskjaer said: “He’s come back bright, confident and with lots of energy. I think everyone saw what he did at the end of last season with West Ham.
“He’s still in my plans. I expect him at Man Utd at the start of the season.”
It comes as a massive blow for West Ham, keen on tying Lingard to a permanent loan deal.
United commenced their preseason with a win over Derby County, and Lingard came in a substitute in the second half.
Lingard’s presence will strengthen United’s midfield option, but whether he can beat Bruno Fernandes for the attacking midfielder role remains to be seen.
The Portuguese was arguably one of the best players for the Red Devils last term but suffered a dip in his performance in the European Championship.
