That is the view of ESPN journalist Mark Ogden, who was speaking after Chelsea’s loss to Manchester City yesterday.
The Blues were beaten by a solitary second-half goal from Kevin De Bruyne.
Morata was substituted in the first-half after pulling up with a hamstring injury.
The Spaniard had been in fine form since his arrival from Real Madrid in the summer, scoring a hat-trick in his previous Premier League outing against Stoke.
And Ogden says Antonio Conte must now decide who is the best option through the middle in Chelsea’s upcoming matches.

“I think the loss of Morata made all the difference,” Ogden told ESPN FC.
“I think prior to that I think Chelsea were happy to hit City on the counter attack.
“They had the people to do it with Morata in the team.
“Once Morata went off they were toothless. I think that it showed that Chelsea have got a problem there.
“If Morata is injured for a length of time, how do they replace him?
“Where are the goals going to come from?
“It’s a massive injury and I think it showed tonight that if he is out for a long time, they will have problems.”
