Romelu Lukaku is the league’s top scorer with 24 goals to his credit so far, but there are still doubts about his capabilities due to how he misses out in big games.
The 23-year-old has often gone missing when playing against the top six, and Gary Neville has warned Chelsea about a potential summer deal.
Neville told Sky Sports’ podcast: “The question mark and frustration with Lukaku is ‘does he do it in the big games?’
“That won’t go away until he moves to a big club and starts delivering.”
Lukaku has made it clear that he wants to leave Everton at the end of the season and refused to sign a new bumper contract in March.
The Toffees are reportedly holding out for a £70 million fee for the Belgian.
