United's attempts to sign the Portugal international looked to have failed in the final hours, with the paperwork not completed. A statement was released by Primera Division officials, but was subsequently retracted.
The Spanish giants were prepared to let the 25-year-old move on, though, but only if they could bring in a replacement left-back. Guilherme Siqueira, who was available from Granada, was their top target.
By the time United firmed up their interest, Granada had agreed to loan Siqueira to Benfica - and subsequently Real decided not to sanction Coentrao's switch.
