The Blues signed the Spain international in a £60m deal from La Liga giants Real Madrid last summer to improve their attacking options ahead of the 2017-18 season.
The Chelsea FC summer signing made an encouraging start to his Blues career with nine goals in eight games in all competitions.
However, Morata suffered a loss of form and a number of injury setbacks to curtail his promising start to the Premier League season.
The 25-year-old striker scored 11 goals and made six assists in 30 appearances in the Premier League this season.
Morata has been linked with a potential return to Juventus in the summer following his challenging debut campaign.
Former Chelsea FC star Cascarino believes Morata needs to take his shots early if the Spanish forward wants to improve at the west London side.
“Alvaro Morata does so many good things on the pitch,” Cascarino wrote in his column in The Times.
“But he just needs to learn to get the ball out of his feet more quickly and shoot.
“Sometimes the Chelsea striker seems to be waiting for the perfect situation to arise before he takes aim at goal.
“To be a great centre forward you need to hit the ball early and try to break the net.
“When he was played through on goal in the first half last night he might have scored had he shot quickly and surprised Jonas Lossl, the Huddersfield goalkeeper.
“Instead he took it around Lossl and the angle became too acute.”
Chelsea FC played out a 1-1 draw with Huddersfield Town in the Premier League at Stamford Bridge on Thursday night.
The Blues signed England star Ross Barkley, AS Roma defender Emerson Palmieri and Arsenal striker Olivier Giroud in the January transfer window.
