Everton manager Roberto Martinez has challenged striker Romelu Lukaku to maintain consistency following the Belgian's hat-trick against Young Boys in the Europa League.

The Spaniard has called upon the forward to replicate his goalscoring form in the Premier League, starting with this weekend's clash with Leicester City.

"I thought Romelu was unstoppable at times. It wasn't just scoring the hat-trick, it was creating the amount of chances that we created as a team and he was always in the right place with the right run," Sky Sports News quotes him as saying.

"He could easily have scored six. Probably he scored the hardest chances out of all the good opportunities we created.

"But what pleases me is the responsibility that he took. He led the line fantastically well, the combination play in front of their goal was based around him, and that chemistry with the players around him pleased me a lot."

Everton head into the meeting with Leicester in 12th place in the table, while the Foxes are rooted to the bottom.
