The Croatian has enjoyed a fine first season with the Hammers.
The former Croatia boss has enjoyed an impressive first season in charge at Upton Park, with the Hammers flourishing under his guidance.
They currently sit sixth in the table, just four points away from Manchester City in fourth and five from rivals Arsenal in third.
That leaves them with a strong chance of finishing in the Champions League places come the end of the season, while they also have their eye on FA Cup glory.
And Parker has praised Bilic for the work he has done, while also saying credit should go to the owners for making the appointment.
“Slaven Bilic has done an unbelievable job since taking charge last summer and you have to give credit to the owners for the appointment,” he told whufc.com.
“Slaven has quickly blended together a very good squad. They always look a threat going forward and, as a former West Ham player, I am so pleased that everyone at the club is having such a good time.”
“I honestly don’t think there is a team in the Premier League who would relish playing against Slaven’s West Ham nowadays. Even teams like Manchester United, Arsenal and my old club Chelsea.”
The Hammers will now be hoping they can continue their current excellent run of form and make it into the top four.
However, the FA Cup may get in the way of that, with them keen to go all the way in that competition and win it is as the perfect send off for Upton Park.
Indeed, everyone at the club, including captain Mark Noble has already hinted that is their man aim as the campaign comes to a close.
