Chelsea coach Antonio Conte also stressed the importance of hard work ahead of a heavier schedule involving European competition.
He said, "Morata is a fantastic young striker".
Morata made his mark on the game 13 minutes later, flicking on a corner for Michy Batshuayi to finish. They will have to...
He said: "It's too early to speak about the impact of Morata".
The start of the second half had a similar look to the opening 30 minutes as Bayern regained control, with new signing James Rodriguez squandering three chances to put the game to bed.
'We need to give him the right time to adapt to our way of football but he must be pleased with his performance'.
"Our start wasn't good but I think the players showed great willingness to try and change the result".
Morata came on to make his first appearance in a Blues shirt 15 minutes into the second half, going out to the left with Batshuayi continuing to spearhead the attack.
"At this moment Renato is training with us, is working with us", added Ancelotti.
Chelsea took on Bayern Munich in China, hoping to build on their impressive 3-0 victory over Arsenal at the weekend.
Antonio Conte's men only trailed by two goals by the time Chelsea's most expensive player finally entered the action, with Marcos Alonso having lifted the Blues' beleaguered spirits with a sweet strike just before the interval. "I'm looking to work hard, score as many goals as I can and to win as many trophies as possible".
