It’s time. Jurgen Klinsmann must go.

He now is inflicting real damage on the U.S. national soccer team.

The U.S. Soccer Federation really has only One Job that fans insist it complete:

Qualification for the Fifa World Cup.

A limp and lifeless U.S. team was crushed 4-0 in Costa Rica tonight. The U.S. has lost in Costa Rica before, but not like this.

That is two defeats in two final-round qualifying matches for the U.S., leaving them at the bottom of the six-nation “Hexagonal” with 0 points and a goal-differential of minus-5.

It is not too late for the U.S. team to rally in its final eight matches, next year, and finish in the top three of the hex and gain direct qualifying for Russia 2018. Or even finish fourth and reach a playoff against Asia’s fifth-best qualifier.

But the federation cannot allow Klinsmann to take this team into a bigger hole than he has already dug.

After the match, U.S. national team player Taylor Twellman wondered if Klinsmann has “lost the locker room”. Former U.S. star forward Brian McBride suggested the Yanks were “overrun” by Costa Rica. He added: “For a U.S. team to be put in that situation, I’m quite surprised.”

I have been agitating for Klinsmann’s ouster since the U.S. loss to Jamaica in the semifinals of the 2015 Gold Cup.

Things have gotten worse since then. A shootout loss to Panama in the third-place game of that tournament. A 3-2 home-soil loss to Mexico in the Confederations Cup playoff. The 2-1 loss to Mexico in Columbus last week.

During his tenure coaching the U.S. team, which goes back to 2011, Klinsmann mixed in interesting victories, now and then — mostly beating good teams in friendlies, the soccer equivalent of exhibition games.

He was not so successful in “full internationals”. He seemed to make up tactics on the fly, had players change positions willy-nilly and made  questionable personnel decisions — from leaving Landon Donovan off the 2014 World Cup team on down.

Now, it appears his team has quit on him, which is particularly telling given that several members on the current squad were discovered by Klinsmann in Germany — the “Germericans” who were supposed to plug the talent gap Klinsmann saw in players from Major League Soccer.

Sunil Gulati, president of the U.S. Soccer Federation, should now be feeling some heat. The coach he pursued and hired and paid extravagantly has failed. If this team misses a World Cup for the first time since 1986, it is on his head.

It is time for Gulati to act.

Bruce Arena, former U.S. national coach, is available. His contract with the LA Galaxy is up. Arena got the U.S. to the quarterfinals of the 2002 World Cup, but he is not the only coach who would be an improvement on Klinsmann.

Gulati must make the call. After the 4-0 embarrassment, he declined to make his customary endorsement of Klinsmann, and he is aware the national team will not resume qualifying until late March. This is the last best time to replace Klinsmann.

Perhaps Gulati has remembered that the U.S. federation has only One Job.

It is time to entrust someone else to revive the U.S. team and reach Russia 2018.
