Ole Gunnar Solskjaer has reportedly told the Manchester United board that he is after four new players ahead of next season.
The 46-year-old is expected to be confirmed as the Red Devils' new permanent manager in the coming weeks after making a huge impact during his caretaker stint.
Solskjaer has worked miracles since replacing Jose Mourinho in December, dragging United right back into top-four contention in the Premier League and through to the quarter-finals of the Champions League and FA Cup.
According to Metro, however, the Norwegian still has concerns about the quality of his squad and wants a quartet of signings to help mount a title challenge next season.
A right-winger, attacking midfielder, left-back and right-back are all said to have been lined up by Solskjaer, with the recruitment of the latter expected to be made a priority.
United are likely to offload Matteo Darmian and Antonio Valencia in the summer, while Ashley Young will turn 34 later this year.
Solskjaer apparently made the demands during a meeting with his bosses in London last month.
