TTottenham’s Dutch striker Vincent Janssen suffered ‘a 20 minute loss of memory’ after a clash with Belgium goalkeeper Simon Mignolet in Wednesday night’s international friendly, it has been revealed.

Janssen suffered the injury in the first half of the 1-1 draw in Amsterdam when Mignolet came out to clear a short back pass from Laurent Ciman and clattered into the onrushing striker.
Janssen was forced off shortly afterwards and Holland manager Danny Blind has confirmed the 22 year old had suffered memory loss after the incident."He cannot remember a period of 20 minutes,” said Blind. “That's not good, of course. With a head injury you have to be careful.”
The news will also be a concern to Tottenham manager Mauricio Pochettino, who signed Janssen from Az Alkmaar for a fee of £18.5m this summer.
Janssen has struggled to make an impact at White Hart Lane so far, with all three of his goals for the club coming from the penalty spot.But Pochettino has backed Janssen, saying at the end of last month that it was only a matter of time before he began to find his scoring touch.
“We are very happy with him," Mauricio Pochettino said after the EFL Cup defeat to Liverpool.
"We need to understand that he's 22, he's come in from the Netherlands, a different league, and we always need to give time."But one thing is clear, he is a player who works a lot, who is always involved, and the commitment he shows in every game and every training session is fantastic.”
Tottenham’s first game after the international break is against West Ham at White Hart Lane, while it remains to be seen whether Janssen will feature in Holland’s World Cup qualifier against Luxembourg on Sunday.
