Chelsea manager Maurizio Sarri admitted it will be hard to deny Eden Hazard a move to Real Madrid this summer, even if a reported £100 million ($130 million) move is "too cheap" for the Belgian captain.
Hazard was in stunning form as the Blues moved up to third in the Premier League, scoring both goals in a 2-0 win over West Ham on Monday.
He admitted his first goal was "something special" as after collecting the ball just inside the West Ham half, Hazard jinked past three defenders before coolly slotting home.
However, Chelsea may be forced to cash in on their prized asset as their number 10 has just over one year left on his contract and has so far refused to extend his deal.
Should they refuse to sell this summer, Chelsea run the risk of losing their top scorer on a free transfer in 2020.
"It (£100m) is too cheap in this market! We have seen in the last few windows every price I think," Sarri said.
"I'm sure the club doesn't want to sell him, but of course we all have to respect his decision, I think.
"He is in the last season of contract, if he wants to have another experience we have to respect it. We will try in any way to convince him, but it is not easy."
The prospect of losing Hazard is even more daunting for Chelsea as they are currently banned from signing any new players due to a one-year transfer ban imposed by FIFA.
"From the technical point of view no, not at the moment," added Sarri when asked if Chelsea can cope without Hazard.
"Also because it is impossible to find another Hazard. At the moment there is not another Hazard, because the level is too high."
Victory ensured Chelsea moved into third in the Premier League, two points clear of Tottenham and three ahead of fifth-placed Arsenal in the race for a top-four finish.
Both their London rivals and Manchester United -- five points back in sixth -- now have a game in hand on Sarri's men.
