France have secured their place in the quarter-finals of the Under-20 World Cup with a 4-1 win over hosts Turkey.

Pierre Mankowski's side were ahead in the 18th minute when reported Premier League target Geoffrey Kondogbia fired them into the lead from close range.

They doubled their advantage before half time when Jean-Christophe Bahebeck turned in Lucas Digne's cross at the near post.

After the break, France spurned the chance to go three goals up when Florian Thauvin smashed a penalty over the bar.

However, new Arsenal signing Yaya Sanogo soon made it three when he raced onto a through ball and dispatched his effort past Akyut Ozer.

Jordan Veretout put Mankowski's side out of sight when he turned in Dimitri Foulquier's cross high into the net in the 73rd minute.

Sanin Bakis scored a late consolation for his side with a neat finish inside the six-yard box but France secured a comfortable victory to reach the last eight of the competition.
