Chelsea striker Alvaro Morata has been a revelation since joining the Blues from Real Madrid over the summer.
Fans at Stamford Bridge were expecting the champions to struggle without Diego Costa, who fell out with Antonio Conte over the summer.
He was top scorer in each of his three seasons in West London but recently returned to Atletico Madrid in a huge £57m deal.
Morata - who has netted six goals in his first seven league games - was forced off through injury during the 1-0 defeat by Manchester City prior to the international break.
The 24-year-old has a grade two hamstring tear and is expected to miss this weekend's Premier League clash against Crystal Palace.
Morata looked rusty in the Community Shield loss to Arsenal in August, missing a penalty in the shoot-out defeat.
He's been unstoppable since coming off the bench on the opening day of the season against Burnley and has quickly become a fans favourite at Stamford Bridge.
Le Saux surprised by Morata's raw speed
The former Real Madrid and Juventus forward is certainly not renowned for his electric pace but has proved he can shift since moving to England.
Ex Chelsea full-back Graeme Le Saux spoke very highly of Chelsea's new star striker, as per football.london.
"I think Morata has surprised a lot of people with how well he’s started but wherever he’s gone, he’s always scored goals. I didn’t expect him to possess such pace and that’s a vital asset in the Premier League," Le Saux told Betfair.
Le Saux also believes the club-record signing is better than his goalscoring predecessor.
"On early evidence he’s probably got more versatility than Diego Costa had so for me I’d side with Morata."
Signed for £32m in 2016, Michy Batshuayi is the only other recognised senior striker in the ranks but was surprisingly overlooked during the defeat at home to Manchester City.
Substituting the injured Morata, Conte elected to bring Willian on instead and Batshuayi may well start from the bench against Crystal Palace.
"I want to succeed at this club and my relationship with Alvaro is very healthy," said the 24-year-old Belgian striker.
"I don't want to leave during the next transfer window, because we're going to play a lot of games and I will certainly get an opportunity."
