The 18-year-old has scored four goals in his last three appearances and the Norwegian coach is relieved to have him as the campaign heats up
Ole Gunnar Solskjaer has been impressed by the fearlessness Mason Greenwood has shown in attack for Manchester United this season.
The 18-year-old has scored 16 goals for the Red Devils in all competitions and has been in particularly good form in the last two weeks, netting four times in three games to help Solskjaer's men stretch their unbeaten run to 10 matches.
The campaign is growing more intense for United as they continue to fight for a place in next season's Champions League and remain in contention for the FA Cup - facing Chelsea in the semi-finals next Sunday - as well as the Europa League.
