Thomas Tuchel admits the secret to coaxing more from record signing Romelu Lukaku is not simply a one-step solution.
Lukaku has scored once in five appearances since he was recalled after being dropped from a game against Liverpool for public comments bemoaning Tuchel's tactical system.
He was unable to find the net against Manchester City or Brighton or in either leg of the Carabao Cup semi final against Tottenham but he did find a goal in the FA Cup against Chesterfield of the National League.

'I don't know if I can explain it,' said Tuchel when asked what was wrong with Lukaku, who is not only short on goals but also low on involvement, and he was replaced with 10 minutes to go as Chelsea searched for a winner in a 1-1 draw at Brighton on Tuesday.
