Wigan Athletic boss Roberto Martinez aims to add one more signing to his squad before the market deadline falls.

Martinez has already made four additions to his group this summer, recruiting defender Ivan Ramis, midfielder Fraser Fyvie and striker Arouna Kone on permanent deals from Real Mallorca, Aberdeen and Levante respectively, and Arsenal winger Ryo Miyaichi on a season-long loan.

And he revealed one more player could come in before the transfer window closes.

"At the moment, we are still looking at if we can bring in maybe another player, but it has to be the right one and he has to be the right character to fit in," Martinez said.
