Paraguay boss Gerard Martino has identified Japan’s counter-attack as a potential threat in their last-16 clash in the World Cup.

The Japanese have surprised many in South Africa and Martino has warned his side that any lack of concentration will be punished as both sides aim to make the quarter-finals for the first time.

He said: “Fundamentally they are a team who get back into their defensive positions very well, using a back-line of four and practically five midfielders, with Honda generally up front.

“When they get the ball they come out very quickly on the counter-attack, this is what we have to be careful of most, the fast breaks.”
