Manchester United are likely to limit their summer spending to three or four key signings.
United will be in the Champions League and boss Jose Mourinho said executive vice-chairman Ed Woodward has had his targets "for more than two months".
Mourinho wants to enhance his forward and defensive options to challenge for the Premier League title next season.
United have been linked with Atletico Madrid striker Antoine Griezmann and Burnley centre-back Michael Keane.
"Ed Woodward has my list," the Portuguese manager said after his side beat Ajax to win the Europa League for the first time on Wednesday.
