Carlo Ancelotti was left with mixed feelings after his Real Madrid side came from behind to beat Levante on Saturday.
Goals in the 90th and 94th minutes from Avaro Morata and Cristiano Ronaldo gave Los Blancos a 3-2 win over the Granotes.
"We have to review this match, because it was not good from a tactical and technical point of view,” he told a Press conference.
“We reacted fantastically at the end of the match. With players with that attitude, fighting all the time, the game is not hard to improve and we need to.
“The win was very important because the match was very difficult. At the end we did not give up and that gave us the three points.
“It is true that we did not play fantastic football, but we deserved to win in the end".
“[The young players] do need not need to convince me of anything because I already have enough confidence in them.
“They were enthusiastic when they went on the field and did well. Morata scored and Jese was very dangerous. The confidence is the same. Morata can play. He does not have Benzema’s experience, but he is young, he is enthusiastic and is very important for us.
"The first half was not good but the second half was different. We conceded two goals when we needed to concentrate more.
“We gave away two goals and the match became tougher. The players made a big sacrifice at the end and when the team plays like that it is easier to win the match".
