Manchester United were reportedly prepared to pay up to €50m (£45m) to sign Bayer Leverkusen attacker Moussa Diaby during the summer transfer window.
The 21-year-old enjoyed a productive 2019-20 campaign for Leverkusen, scoring eight times and contributing eight assists in 39 appearances in all competitions.
According to Bild, United identified Diaby as a possible transfer target over the summer, and the 20-time English champions were prepared to pay as much as €50m (£45m) to sign him.
However, the report claims that Leverkusen signalled that they were not prepared to sell the France Under-21 international due to his importance to the side.
The left-sided attacker arrived at BayArena from Paris Saint-Germain in July 2019.
