New York City FC head coach Patrick Vieira still isn’t happy with the referees in MLS.

Often the league’s outlier when it comes to its officiating, Vieira was asked what NYCFC, who were eliminated against the Columbus Crew from playoff contention on Sunday, needed to improve on heading into next season.

His response? The league’s referees.

“When you look at the two legs, you look at the first leg, you look at the sending off and the impact it had on the game,” Vieira said, alluding to the red card issued to centerback Alexander Callens. “The referee again [today] with time. I’m really frustrated.”

Callens was issued a red card in 4-1 loss at Columbus when he raised his elbow to the face of Columbus midfielder Justin Meram. After the play was blown dead, the referee went to video-assisted review and issued Callens a straight red card that changed the game — and series — for NYCFC.

“We tried to build a relationship with the referees, we spend time when they come into our preseason and we have to stop training,” Vieira ranted. “We have to make our program around them and they’re sending us all these kind of conduct and yellow cards and players who try to lose time. They’re telling us one thing and they’re doing something completely different. So, I hope the referees will be better next year, but I suppose everybody is learning.”

Vieira, who has one year remaining on his contract with NYCFC, also said he has no plans to leave the club despite rumored interest overseas.

“I’m going to be a part of it [next season],” he said.

Andrea Pirlo likely played his last game for NYCFC on Sunday.

Pirlo, 38, made a 90th minute cameo as he came on as a substitute in the 2-0 win against the Crew, playing the final five minutes before the Crew eliminated NYCFC on aggregate.

It was Pirlo’s first appearance since September. Despite previous reports regarding his retirement, Pirlo hasn’t decided on if this is indeed the end of his illustrious career, however, Sunday’s sendoff certainly looked like his last game for NYCFC.

“I think [Pirlo] has meant a lot to this football club,” Vieira said after the match. “He’s been a professional. He’s been a really good example for the young players that we have on our team and if they conduct themselves like Andrea, I think they will have a good career.”
