And Morata coolly clipped the ball beyond the advancing Schmeichel with an assuredness unbefitting of a striker who had gone 13 games without a goal.
Despite going in front, Conte still withdrew Tiemoue Bakayoko at half-time after another awful 45 minutes for the Frenchman in a desperately disappointing debut season in English football following a £40 million move from Monaco.

The visitors were happy to take their chances on the counter-attack in the second period as they began to feel the after-effects of their run around at Barcelona in midweek.
Leicester’s search for an equaliser was largely laboured and, even when a big chance did arise, Vardy headed wastefully over when completely unmarked inside the area.
However, the England international made amends 15 minutes from time when he forced the ball home at the third attempt after Vicente Iborra’s first two efforts were blocked and then saved by Willy Caballero.
Only a fine low save from Caballero prevented Vardy from turning the tie completely around eight minutes later as both sides settled for extra time.
Crucially, Conte was able to refresh his side as Pedro, Gary Cahill and Olivier Giroud were all introduced in the first half of extra time.
And it was Pedro who proved the match winner in unfamiliar fashion as he rose to outjump Schmeichel and nod into an unguarded net.
