Fonte was excellent as the Hammers saw off Huddersfield 2-0 at the London Stadium on Monday night to pick up their first three points of the new campaign at the fourth attempt.
The 33-year-old has struggled since his £8m move from Southampton last January and eyebrows were raised at his inclusion as part of a back five on Monday but the experienced centre back put in arguably his best performance in claret and blue alongside Winston Reid and James Collins.
Bilic has been at the forefornt of a difficult few weeks for West Ham, with failed moves in the transfer window, poor performances on the pitch and the circus at boardroom level all contributing factors to three straight losses to start the season.
But, Bilic got it spot on at the London Stadium earlier this week and Fonte was not surprised as he backed the boss. West Ham co-owner David Sullivan threw Bilic under a bus with a recent statement on transfers and his refusal to sanction the purchase of William Carvalho which led to a pathetic spat with Sporting Lisbon.
Fonte said: “He is a passionate manager and a great manager and he deserved this because he’s been under a lot of pressure, of course, as we all know. This is the business that we are in.
“It was important for him and it was important for us to show our attitude and that we are always with our manager and I’m pleased for him because it was his birthday and we gave him what he wanted.
“We are experienced enough to know we are all under pressure. This is our job and we get criticised for everything, so the best way to deal with it is to go to the training ground and work harder than ever and that’s what we’ve been doing, training as hard as we can to put things right.”
