Willian believes that Hazard will still be in Stamford Bridge by next season.
Hazard fired the winning spot-kick on Thursday as Chelsea edged out Eintracht Frankfurt 4-3 on penalties to book Europa League final against Arsenal.
The Belgium forward is being expected to join Real Madrid in a big-money move this summer.
Willian, however, continues to hope otherwise.
Asked if Hazard’s decisive penalty could prove his last kick at Stamford Bridge, Willian told BT Sports, “I don’t know, I don’t think so.
“For me I hope he stays, but in football you never know. I think his head is here, to play for Chelsea. Then after he’s finished the season maybe he can talk about his situation.
“I don’t know anything about him leaving so for me I hope he can stay. He’s very important, a special player, he’s very important for us, he helps us a lot.”
