Roberto Martinez: Everton boss vows to bounce back from poor run

Challenging time for Everton - Martinez

Roberto Martinez says Everton's current run of form is not acceptable but has vowed to bounce back in the second half of the season.

Everton's 2-0 loss at Hull City was their fourth straight Premier League defeat and sees them drop to 13th, four points above the relegation zone.

"This is a challenging time but we need to look forward to the second half of the season," said Martinez.

"As a football club we can never accept the run of results that we've had."

Goals from Ahmed Elmohamady and Nikica Jelavic were enough to see off the slumping Toffees at the KC Stadium on New Year's Day.

That result came on the back of defeats to Southampton,Stoke City and Newcastle United in a troubled 12-day festive period.

"We need to work as hard as we can. Yes, we have some injuries, but we have the talent that we used so well last season. We know what we can achieve," Martinez added.

"Clearly the performance today, after letting the first goal in, was not up to the standards we expect. There's no panic but we're not happy.

"It is a tough period but the reality is that the second half of the season is an opportunity to get back our swagger and our enjoyment and get a positive result really quickly."
