BOYS TWO MEN Man City 1 Man Utd 2: Garnacho and Mainoo stun title winners in FA Cup final to give Ten Hag perfect send-off .

HERE, in what was likely to be his last match as Manchester United manager, was Erik ten Hag’s ‘football bloody hell!’ moment. 

In one of the greatest FA Cup final upsets of recent times, Manchester City blew their chance of an historic ‘double Double’ as first-half goals from Alejandro Garnacho and Kobbie Mainoo sunk Pep Guardiola’s champions.  

In 135 years of English football history, no club has ever retained both the league title and the FA Cup in the same season. 

And, thanks to a tactical masterclass from their Dutch manager, United gleefully wrecked the party of the one-time ‘noisy neighbours’ who have dominated them for the last decade. 

It was Ten Hag’s second trophy in as many seasons and it was the first time since Sir Alex Ferguson’s era that United had triumphed in a cup final against the odds. 

In the last largely-barren 11 seasons, United had beaten Crystal Palace, Southampton, Ajax and Newcastle to win trophies. 

But this was the most impressive by far - at the end of a staggering Cup win which included the epic 4-3 defeat of Liverpool and the extraordinary semi-final which saw United chuck away a 3-0 lead against Coventry only to escape a last-gasp defeat courtesy of a cruel VAR call.

Ten Hag played without an authentic centre-forward, sucked City in and triumphed due to two long diagonal passes which stretched their rivals’ defence and led to those first-half goals. 

Jeremy Doku set up a nervy finale with an 87th-minute strike but United held on through seven minutes of injury-time. 

Ten Hag is likely to go irrespective of this famous win due to a lowest-ever eighth-placed Premier League finish as well as the humiliation of exiting Europe before Christmas.
