Everton goalkeeper Tim Howard has insisted that he is 'not worried' about the day that on-loan striker Romelu Lukaku may have to return to parent club Chelsea.

The Belgium international moved to Merseyside on a temporary basis before the campaign, but it is unclear whether Lukaku will return to Stamford Bridge after failing to break into the first team.

"The one thing with all good managers that Roberto Martinez shares is that he has a belief in his own ideas and his ability," Howard told talkSPORT.

"If Big Rom has to go, or Nikica Jelavic has to be replaced, I think he believes in his ability to recruit players, so I don't worry about that."

Lukaku signed for Chelsea from Anderlecht in 2011.
