After yesterday's victory, Lautaro spoke to Urawa Reds in their club World Cup -similar game.
The striker said: “We studied this match, we knew it would be. All ten of them were behind the ball, they left the game to us and it was a match with many difficulties.
“When we gave a goal that we had to chase, but we continued to play despite the difficulties. We have to improve, with a shot on the goal they scored against us and we have to improve a lot.
“We have to give a little more, sometimes dribbling is not enough. We certainly did very well in the second half.”
Lautaro added: “Chivu gives us a lot, we help him a lot. We have to make our contribution, the most important thing is that we have to believe in everything he tells us. He is an excellent coach, prepared and he surprised me a lot.”
