Angel di Maria is also valued at £40m, but wants to play Champions League football
Another high profile target for United is Real Madrid star di Maria, but their pursuit of the Argentine has hit a stumbling block due to their lack of top European football next season.
The Mirror reports that whilst the 26-year-old is likely to leave the Estadio Santiago Bernabeu this summer the midfielder is keen to continue playing Champions League football.
Di Maria has entered a stalemate with Madrid over contract talks and both Paris Saint-Germain and Juve have also shown interest in the South American.
