Nigeria coach Thomas Dennerby believes there is still work to do on VAR after his side lost 3-0 to Germany in the last 16 of the Women's World Cup.

The use of the technology has aroused debate at this tournament, and referee Yoshimi Yamashita referred to the video replays for Germany's opener and then their penalty.

"There have been some strange situations of course," said the Super Falcons coach. "There was one time in the first half when no-one knows what they were watching for, players looking at each other, coaches looking at each other.

"Goal-line technology is good for the game but I don't think anyone has the final solution for VAR yet - but it did not affect our team."

Alexandra Popp's header gave Germany the lead in the 20th minute, and the goal was only allowed to stand after Yamashita decided Svenja Huth was not interfering in play while in an offside position.

Then, following another VAR check, the Japanese official awarded a penalty, having ruled that Evelyn Nwabuoku had fouled Lina Magull.

Sara Dabritz converted from the spot before Lea Schuller fired in a late third for the two-time champions.

Germany coach Martina Voss-Tecklenburg said: "Maybe we can speed up the whole process when VAR is used but if the time is needed we have to accept it.

"It was positive for us twice so maybe I'll approach it in a positive way. But there were quite a lot of interruptions."

Either Sweden or Canada stand between the two-time winners and a place in the semi-finals.

During this tournament, criticism has been directed at the new directive saying punishments should be issued for goalkeepers who come off their line for penalties, which had an impact on both Scotland and Nigeria's results in France.

However, during Saturday's first quarter-final in Grenoble, it was the Japanese official's interpretations that raised debate.

Popp's opener from Magull's corner appeared good until VAR alerted Yamashita to a possible issue over Huth's offside position in front of keeper Chiamaka Nnadozie. After a check, the referee allowed the goal to stand.

Moments after the restart, Magull hit the deck when Nwabuoku unintentionally caught her in an attempt to clear the ball. Yamashita signalled a throw-in but once more received a message from the VAR team.

It was three minutes before Yamashita changed her decision to a spot-kick, which Dabritz put away to give the Germans a 2-0 lead.

The second half was less eventful. Had Desire Oparanozie timed her stretch to turn in substitute Rasheedat Ajibade's low cross then it would have set up a far more tense finish.

Instead, SGS Essen forward Schuller put the game beyond the reach of the Super Falcons with an angled strike that nestled in Nnadozie's right-hand corner.

Former England defender Casey Stoney speaking on ´óÏó´«Ã½ Two about the opening goal: "I genuinely cannot understand what is going on in this tournament. When Popp makes contact, Huth is in line with the keeper's vision - that has to be offside. How can we not deem that offside?

On the penalty from which Germany scored:"The referee had to see this. If you are in a good position, you see that it is a penalty. You should not need to go to VAR for that to be given and waste even more time. So I am questioning the ability of the officials at this tournament."

Former England defender Laura Bassett on ´óÏó´«Ã½ Two: "The referees are using VAR as a comfort blanket - 'Please back me up, I don't want to get this wrong'. But that's not good enough. That's not what it is there for."
