Tottenham’s Vincent Janssen lost his memory for 20 minutes after a crushing clash with Simon Mignolet in Holland and Belgium’s friendly on Wednesday night.

Belgium keeper Mignolet was strong in an aerial challenge with the Dutch striker, punching the ball away but collecting Janssen on the way through.

Janssen hit the ground and stayed down before leaving the pitch after 25 minutes and played no further part in the match and will be in serious for Sunday's World Cup qualifier against Luxembourg.

Holland boss Danny Blind later expressed concern over his striker, saying he had no idea what had happened.

"Vincent Janssen is going to be a very difficult story," Blind said.

"The physician told me it is a concussion. He lost 20 minutes of his memory, and doesn't know what happened.

"We have to be careful with that and talk it through."

In the absence of his striker Holland found it tough to create chances but found the opener with a 38th-minute penalty from Davy Klaassen after an ill-advised challenge from Jan Vertonghen.

Yannick Carrasco deflected the equaliser inside the final 10 minutes for a 1-1 draw.

Earlier, Vincent Kompany was set to start and on the Belgium team sheet but in another apparent injury blow for the Manchester City captain he was withdrawn 30 minutes later.
