Gonzalo Higuain will have more of an impact at Chelsea when he begins to develop more of an understanding with his team-mates, according to Gianfranco Zola.
The Argentina striker made his Blues debut on Sunday , selected from the start for the 3-0 FA Cup fourth-round win over Sheffield Wednesday at Stamford Bridge.
Higuain arrived on loan at the club from Juventus on Wednesday and was a peripheral figure against the Owls as the holders cruised into the last 16 thanks to Willian's brace and a fine effort from Callum Hudson-Odoi.
The 31-year-old turned down the chance for a goal in his first game, rejecting Willian's offer to take the 26th-minute penalty that put Chelsea ahead.
