David De Gea’s  move from Manchester United to Real Madrid has collapsed because the necessary paperwork was not submitted in time, the BBC reports.

No official announcement has yet been made by either club.

As part of the deal to sell De Gea to Real, United were planning to bring Keylor Navas in the opposite direction.

There is no precedent for Spanish clubs being given additional time to conclude transfers as there is in England.

Blame for the failure to complete the deal is already being apportioned.
