The club have exercised their option to tie down the goalkeeper for an extra 12 months amid continued talks to agree a new longer-term deal
Manchester United have exercised their right to extend David de Gea's contract for an additional year, tying the Spain international to Old Trafford until 2020.
The Spaniard signed a new four-year contract in September 2015, just days after a proposed move to Real Madrid was scuppered on transfer deadline day.
And as has been recent club policy, United included the ability for them to add a further year to the goalkeeper's deal to hold onto him until the end of the 2019-20 season.
