Wigan Athletic boss Roberto Martinez is yet to make decisions over his transfer needs.

Martinez will wait for the first couple of weeks of preseason before plunging.

"The best news of the transfer window for us is keeping the core of the squad together, something that has been the main aim for this period and something we're all very excited about," he told the club's official website.

"Over the next week I want to see how the players return and respond to the work ahead. After that we'll look to make some additions to the squad.

"I do feel as though we need at least two players with experience and a younger face which will help to make the perfect number of the group."
