Crystal Palace stunned Manchester United as Patrick van Aanholt scored an injury-time winner to record their first victory at Old Trafford since 1989.
Playing at Old Trafford in the Premier League for his fourth different club, Cahill was celebrating his first win.
He made only two league appearances for Chelsea last season, so the 33-year-old could be forgiven an element of rustiness, although it was pure pace from Martial that caused the centre-back to drag the forward down as the hosts searched for a quick equaliser.
Cahill could easily have been sent off. Instead, he remained on the pitch and used his experience to steer Palace to an unexpected victory.
Eagles manager Roy Hodgson is too experienced to get carried away by one game – but given his side were yet to score this season and had lost five of their past six visits to Old Trafford, the the former England boss surely cannot have travelled with much confidence.
But they now sit level with United on points, and with Cahill easing himself in after his summer move from Chelsea, Hodgson could have one of the season’s best free transfers at their disposal.
Man of the match – Gary Cahill (Crystal Palace)
Palace break records – the stats
- Manchester United have won only one of their past nine matches, scoring just eight goals and conceding 16.
- Palace’s Van Aanholt became only the second player to score a 90th-minute winner against United in the Premier League after Thierry Henry for Arsenal in January 2007, and the first to do so at Old Trafford.
- Crystal Palace earned their first win over Manchester United in the Premier League in their 21st meeting in the competition, and their first in the league since May 1991 (3-0 at Selhurst Park).
- United are only the second team to win a penalty in each of their first three matches of a Premier League season, after Chelsea in 2012-13. However, the Blues scored all three of theirs while the Red Devils have missed two.
- Since the start of last season, Crystal Palace have earned 60% of their points in the league in away games (32 out of 53), more than any other side.
- James is the seventh Manchester United player to score in his first two Premier League appearances at Old Trafford for the club.
- Ayew’s opener for Crystal Palace came from their first shot and first touch in the opposition’s box.
- Rashford’s long-range effort in the 58th minute was the latest United have attempted their first shot on target of a Premier League game at Old Trafford since April 2017 against West Brom (67th minute).
