Wigan Athletic boss Roberto Martinez admits he needs a new defensive signing.

Wigan have been linked with both Wolves defender Roland Zubar and Liverpool 's Sebastian Coates, but while Martinez refused to confirm his interest in particular players, he admitted there is business to be done.

He said: "I don't like to get into positions where you are desperate to bring one player in in the final week.

"Unfortunately we lost Ivan Ramis in the last away game in the league against Fulham. That's been a position we are already short so it's been something that's forcing us to look around and see if we can find the right personality to come in, but not just any player or any signing.

"We want to be in a position where we can take advantage of the window as the injury surprised us a little bit but my focus goes to trying to get all of the players fully fit and back from injury and trying to play the last third of the competition."
