Wigan Athletic boss Roberto Martinez is demanding his players not slack off with Premiership safety all but secured.

The Latics face Manchester City tomorrow night.

"We cannot afford to look at it that way," Martinez said.

"We need to make sure we finish the season as strong as we can, carry on with the focus and the attention we showed on Saturday and the good football we have been showing throughout the campaign.

"It is not a matter of trying to do just enough to stay in the Premier League.

"There are still 21 points to go and it would be a big mistake if we take it that way."
