HOUSTON, June 29 (Reuters) - Patience ⁠and a change of strategy at halftime were the secrets to Brazil’s last-gasp 2-1 victory ⁠over Japan in Houston on Monday that sealed a place in the last 16 ‌of the World Cup, according to coach Carlo Ancelotti.

Brazil turned around a deficit in a World Cup knockout game for the first time since beating England 2-1 in the quarter-finals in 2002, as a goal from Gabriel Martinelli in the ​95th minute defeated a Japan side that had proven stubborn.

Ancelotti said ⁠the belief was always there they ⁠would score, but a tweak in tactics at halftime to use more crosses into the box paid ⁠dividends ‌as Casemiro equalised and Brazil seized control of the game.

"This was the most complete game we have played (at the World Cup)," Ancelotti said. "We had trouble in the first half as ⁠Japan were defending well, they were close and tight to us.

"In ​the second half, we overcame ‌it, we got some space and put in crosses. This was an evolution (in tactics) ⁠for sure.

"At halftime I ​said to the players to be patient, because sooner or later we would score a goal. But we had to keep our shape to ensure we did not compromise the game further.

"Japan is a very good team, ⁠very organised, they create dangerous opportunities and get close (defensively). ​They are physical."
