Ajax maintained their Eredivisie title challenge with a comfortable win over 10-man ADO Den Haag today.
The visitors took full advantage of the red card shown to Ali Boussaboun after 26 minutes to claim all three points thanks to goals from Jody Lukoki and Jan Vertonghen.
ADO remain just outside the relegation zone, while Ajax kept up the pressure on AZ Alkmaar at the top of the table.
Ajax had the first chance of the game after four minutes when Christian Eriksen set up Siem De Jong for a shot on target, but his effort was comfortably saved by goalkeeper Gino Coutinho.
With 15 minutes on the clock De Jong then saw another attempt on target blocked by Kenneth Omeruo just in front of the line, before the decisive moment in the contest arrived in the 26th minute.
Boussaboun was shown a straight red card for a bad foul on Vurnon Anita and left his side with a mountain to climb.
Surprisingly the home side did then create the next chance, with Lex Immers firing over, but Ajax had the last chance of the opening period when the influential De Jong shot straight at Coutinho.
It took Ajax just three minutes of the second half to break the deadlock as Theo Janssen set up substitute Lukoki, who had come on at the interval, and he just remained onside and fired the ball into the left-hand corner.
Ismail Aissati then struck the outside of the post after 53 minutes before Ajax made certain of the points just after the hour with a second goal.
Vertonghen ran from inside his own half before playing a one-two with Aissati and curling in a superb shot into the far corner.
The home side tried to get back into the contest and Jens Toonstra set up Tjaronn Chery just moments after going 2-0 down, but Chery's shot was turned wide by Vermeer as Ajax ran out comfortable winners.
