West Ham United are set to face Everton this weekend.
West Ham are set face to the Toffees at Goodison Park tomorrow, and Bilic is under no illusions about how tough a test awaits.
"On paper Everton are amazing and can be one of the best teams in the league on the pitch,” he said. “They have everything and we will need to be at our best ahead of the game tomorrow.”
Everton have actually performed below expectations this season, and they currently sit in 11th place in the Premier League table.
The Toffees have been porous at the back, and their defensive struggles have rather plagued their campaign.
However, Everton have started to hit form in recent weeks and they have won five of their last six matches.
The Toffees also have a striker, in Romelu Lukaku, who has a great scoring record against West Ham, and Bilic knows that the Belgian will have to be carefully watched.
"Lukaku is a dangerous player and is one of the best strikers in the world,” Bilic said. “He has scored six goals in six games against us. But I am confident that the players I have available to me will be able to cope with him.”
When Everton and West Ham met earlier in the season they drew 1-1 at Upton Park.
On that occasion, Manuel Lanzini put Bilic's side in front with a wonderful strike, before Lukaku hit an equaliser.
