Barring a late injury or bout of illness, the Spaniard is poised to become the first non-British player and goalkeeper to make 400 Premier League appearances for one club.
There are non-British footballers with more Premier League appearances than David, but they all tallied over 400 with a selection of clubs. That list includes Mark Schwarzer (514), Sylvain Distin (469), Brad Friedel (450), Shay Given (450), our own John O'Shea (445), Petr Cech (443), Jussi Jaaskelainen (436) and Richard Dunne (431).
While David is focused entirely on performing well against Leeds and helping the team to win three points, the achievement would clearly highlight his commendable longevity since joining United in 2011.
