Everton boss Koeman has said he is unsure if striker Romelu Lukaku will move in the summer, with big interest shown already by Chelsea.
Rumors surrounding the future of Lukaku have been everywhere recently, after the Belgian confirmed he does not intend to sign a new deal with the Toffees, and with his former club Chelsea reportedly very interested in securing a deal for the striker, there is more and more pressure on Koeman to make a decision.
Chelsea are said to be interested in Lukaku even if Diego Costa remains at Stamford Bridge.
Costa was subject to speculation after he reportedly had a bust up with Antonio Conte earlier in the season regarding a big money move to China.
Since then speculation has continued to mount, and it seems this has encouraged Chelsea to look for a potential replacement if Costa does choose to leave, but it is reported that even if Costa remains in West London, Antonio Conte would not be opposed to bringing in Lukaku.
The Dutchman said: “First of all we like to keep the best players, but that’s difficult. I don’t know if it’s possible to keep them. And then we have to analyse the team what we need to improve the team for next season.
“I think we need offensive-wise we need more players, who score more goals because the difference between Lukaku and the rest of the players is too big.
Asked if he was hopeful of having Lukaku next season, the Everton boss added: “I don’t know, we will see what happens at the end of the season.”
