"I haven't been surprised, I am glad for him", said Bilic.
That Chelsea points tally is the best ever in the Premier League, but the class of 2016/17 do have the potential to better it, as they can still in theory finish on 99 points this term.
Chelsea were comfortable and could have further added to their lead, but ultimately could not and also failed to keep a clean sheet as Manuel Lanzini bagged a consolation for West Ham in injury time.
Having seen some of their top six rivals - the title race is really over isn't it - pick up maximum points, Chelsea needed to reassert their dominance at the top of the table with a strong showing, and they did just that with two of their marquee players scoring the goals.
Last season, Victor Moses was plying his trade with West Ham during something of an up-and-down loan spell. "Until now, we have deserved to stay on top of the table".
Chelsea wing-back Victor Moses is now enjoying the best form of his career but the Nigerian admits he needs to take more of his goal-scoring opportunities after he was rewarded with a two-year contract extension earlier this week. Costa has managed to score or assist a goal every 101 minutes this season and that looks ominous for West Ham.

Midfielder N'Golo Kante stole possession deep inside his own half and immediately released Hazard who exchanged passes with Pedro before calmly taking the ball around 'keeper Darren Randolph to slot home his 11th league goal of the season.
"I must have confidence in my players", said the Italian.
Chelsea weathered a mild West Ham storm in the opening 25 minutes before Kante helped carve the hosts open in 10 seconds. Conte has a problem of plenty, especially on the right wing, where Pedro and Willian are fiercely competing for one spot. Eden Hazard (if fit) and Diego Costa should have the space they need to get into top form for the run ahead. The Stamford Bridge outfit may have lost their last game against West Ham, their chances of winning both halves with the betting company goes for (3.57), as they have been priced at odds of (1.44) to score first in this meeting.
DF Winston Reid, 5 - Equally caught out by Chelsea's counter-attacking. "We played under pressure and our answer was very good".
"He was our player previous year and we enjoyed having him here and he also said he had good memories about his time here".
In many ways, Chelsea's route to the title this time around is following a trend set by their most recent success in 2015.
