Despite seeing his side win as he took charge of his first game in Spanish football, the Italian was left unimpressed by his defence's shortcomings at the Santiago Bernabeu
The Italian coach indicated that he was unhappy at the backline as a whole and suggested that goalkeeper Diego Lopez and others may find themselves out of the starting XI for Madrid’s next outing.
“We have to improve. We created chances to score but we had problems in defence,” explained the former PSG boss.
“Today I decided to choose Diego Lopez. I don’t know who is going to play in the next game.
“I have a great squad. [Alvaro] Morata, [Angel] Di Maria and Casemiro made the team stronger tonight [when they came of the bench].”
One thing that did impress Ancelotti was the performance of new signing Isco.
The Spain Under-21 star chose Madrid over Manchester City and others this summer and his new coach praised the playmaker after his goal sealed the points for los Blancos.
“Isco gave it all in this game,” stated the 54-year-old. “He scored a fantastic goal.”
The new Madrid coach was also quick to lament the international break just days before their opening Liga clash, citing it as a further distraction to his side’s preparations for the game against Betis.
He added: “We didn’t have time to prepare for the game due to the international games."
