Watch Ajax fans light flares in huge party as they celebrate Erik ten Hag’s last title before taking charge at Man Utd

AJAX fans celebrated their 36th league title in style as Erik ten Hag led them to victory before preparing to join Manchester United.

Club chief Edwin van der Sar posted a video of the crazy scenes outside the Johan Cruijff Arena in Amsterdam.

Former Old Trafford goalkeeper Van der Sar, 51, posted the video on in the early hours of Thursday morning.

It showed the winning squad dancing on a balcony, some were topless whilst others wore shirts with "KAMPIOEN 36" on the back.

The fans bounced and sung amongst a sea of red with flares lighting the chaos.

He wrote: "Difficult year with everything going on but it ends all good! Thx for support and believe in our club."

Ajax cruised past Heerenveen, destroying them 5-0 at home to move four points clear of rivals PSV Eindhoven.

The win allowed Ten Hag's side to claim the Eredivisie with one game left to play.

The highly-rated Dutchman will take charge of the Red Devils this summer after penning a long-term contract.

After the game, Ten Hag said: “It was a great journey for me here. A beautiful era.

"The results that we got, and the beautiful football that we played.”

The 52-year-old was seen jumping for joy with his bench and hugged every one of his players for one last time at the final whistle. 

He then clapped every corner of the stadium before taking part in the lifting ceremony.

It is his fifth major trophy in five years at the club after also picking up two Dutch cups. 

Man Utd faced angry backlash from fans last week as they tweeted about Ten Hag's side maintaining their advantage in the Eredivisie title.

It didn't help that their United stars had just been battered 4-0 away at Brighton.
