Ronald Koeman says it is on Everton to prove to Romelu Lukaku that they can match his ambition in order to keep him at the club.
The Belgium international is the Premier League’s top scorer with 16 this season, including a superb four-goal haul in the 6-3 home win over Bournemouth last time out.
Koeman said he was unsure whether agent Mino Raiola’s reported claim that Lukaku will sign a new deal was accurate, but welcomed the development.
Koeman thinks Lukaku is as good as it gets in front of goal, but feels the 23-year-old can still improve his all-round game.
He added: “Improving always starts with yourself. He is really a world-class finisher but in other detail, in other qualities, he can and must improve. He knows and that is the most important thing.”
e they are on the rise in order to keep their star striker.
“If the club and team is improving and showing ambition then it is always a good way for players to stay,” Koeman said ahead of Saturday’s trip to play Middlesbrough.
“That is what we need to show him so he is convinced that the future, or the short future, is at Everton.
“Normally players, if they really see a future in a club, if they see the team is improving, the team is getting stronger every day that is always a plus.
“We have had one or two conversations. The most important was at the start of the season when he came back from the Euros and then it was okay.
“You need to explain [your ambition] to players and then they need to see it and you have to show it. At the moment it is really good and that gives players confidence to stay.
