Wigan boss Martinez insists Man Utd can be beaten
The Latics are still fuming after the manner of defeat at Chelsea.
But Martinez insisted: "These fixtures are opportunities to get out of where we are.
"And these six games are real opportunities for us to get the points we need to move up the table. If we'd got the point we should have at Chelsea we would be up to 16th place in the Premier League.
"We've had a lot of bad luck with referees' decisions and hopefully in the next six games we'll get the good luck on our side."
