Boga was surprisingly named in the starting line-up for Chelsea's opening game of the season at home to Burnley.
Tottenham at Wembley is Chelsea's next assignment, and they must now face their most hated rivals without Cahill and Fabregas, as well as Eden Hazard, Tiemoue Bakayoko and the exiled Diego Costa.
And Conte says he isn't anxious about his squad depth.
After just 15 minutes, they were also reduced to ten men when Gary Cahill was given a straight red card. We kept a good shape early in the game, but the sending off makes a big difference.
The visitors shocked Stamford Bridge when they made it 3-0 shortly before half-time when Vokes got his second of the game with a well placed header in the 43rd minute.
Striker Jay Rodriguez, bought from Southampton during the summer for £12 million (NZ$21.3 million), was busy early on for the home side, going close twice in two first-half minutes with a header and a shot.
The Blues didn't come pouring out of the gates, either, though the hour mark saw a decent chance and shouts for a penalty as Burnley got extra chippy. A smart and enthusiastic runner, the Spaniard provided an immediate upgrade on the anonymous Michy Batshuayi and even marked his thankless cameo with an impressive goal, ghosting in at the back post to nod in Willian's inviting cross, before flicking on for Luiz to score.
Nevertheless, Burnley managed to see out the closing stages to claim a famous victory at Stamford Bridge. The Chelsea supporters vented their anger towards referee Pawson, while the delirious Burnley fans sang: "We are top of the league!" That it took until a 2-0 win at Crystal Palace on April 29 to pick up their first away victory says an very bad lot.
