It should have been a moment of pure joy.

Canada, 40 years after playing in their first World Cup, secured their first-ever win at the tournament in emphatic fashion, thrashing Qatar 6-0 in front of a packed and loud Vancouver Stadium.

They are almost certain of a place in the last 32. But celebrations were overshadowed by a dreadful injury to Ismael Kone.

The incident happened eight minutes into the second half, with Canada leading 3-0. Their former Watford midfielder Kone, shortly after receiving the ball, was caught late and badly by Assim Madibo as he challenged for possession.

Kone's reaction, and that of the players around him, said it all.

The 24-year-old Sassuolo midfielder looked anguished and in shock, with his leg visibly broken. His distraught team-mates rushed to him as the referee halted play so the medical staff could come on, while Madibo had his hands on his head.

A scuffle broke out between the two teams as frustration and anger over what had happened bubbled over.

Kone, though, despite suffering an injury that has ended his World Cup, lifted his thumb to the crowd as he was taken off on a stretcher.

"You saw that he was waving to the crowd and almost making everyone at ease," boss Jesse Marsch said after the game.

"It is a statement about Ismael, but also this is an incredible team. I have been telling people for years about the character of this group.

"You got see how everyone was crushed but we had to find a way to stay focus."

Focus they did - as from then on, the crowd and the players were united as Canada pushed on to score three further goals.

During the second-half hydration break, Marsch was in tears. Nathan Saliba - who had replaced Kone - held up his team-mate’s shirt after he scored his side's fourth.

“He will be back stronger than ever and he will continue to have a great career,” said Marsch of Kobe.

“I said at the water break that he would want us to finish this game - and that is what the guys did.”

Marsch confirmed after the game that Kone had gone to hospital, but also revealed that Qatar's Madibo had apologised to the former Marseille midfielder.

"He came into the dressing room to apologise," added Marsch.

"I don't think he meant such a gruesome tackle, I don't fault him for that but I don't understand their reaction from their bench."

Madibo had been sent off for the tackle, leaving Qatar to finish the match with nine men - as Homam El Amin had been sent off for a professional foul on Tajon Buchanan in the first half.

The job is not done yet for Canada but they are within a point of guaranteeing their place in the last 32 of the World Cup - an incredible achievement for a side who had never before registered a point at the tournament until their opening 1-1 draw with Bosnia-Herzegovina.

They next face Switzerland knowing a win will ensure top spot in their group, and staying in Canada for the knockouts.

“You can see the brotherhood,” added Marsch.

“It is one of the first things I noticed when I took on this role, how close they are and how connected they are.

“In a moment like this, I don't think they need me so much, they have each other. Their families are here and we have a family barbecue tomorrow and we will enjoy that and he [Kone] will be on our minds.”
