Manchester United are reportedly considering the possibility of spending £155m on Benfica duo Ruben Dias and Joao Felix.
United are expected to be active in the summer transfer window, and signing a centre-back is known to be high on their list of priorities.
According to Record, that could lead to a £65m approach for Portugal international Dias, who is also attracting interest from other top European clubs.
However, the same report indicates that United may be willing to spend £90m in order to bring highly-regarded prospect Felix to Old Trafford.
The Premier League giants allegedly see the 19-year-old as a potential superstar and may be happy to make an investment in the youngster.
Juventus are also said to be monitoring developments with each player.
