Chelsea youngster Patrick van Aanholt has joined Wigan on a season-long loan, adding depth to Roberto Martinez's squad.
The Holland U21 international has taken in spells at Coventry, Newcastle and Leicester in recent years.
He will spend the remainder of the 2011/12 campaign at the DW Stadium.
The left-back becomes Martinez's third capture in the space of 24 hours, with the Latics having left it late to add to their ranks during the summer transfer window.
"Patrick is a player with enormous potential," said Martinez.
"Technically he is very gifted, very comfortable in possession and physically, he uses his intensity to defend very effectively.
"He can play left-back or left wing-back and without a doubt he's got a phenomenal career ahead of him.
"We rate Patrick really highly and his professionalism and his personal attributes will be a huge asset to us this season.
"Like Tom Cleverley (on loan from Manchester United) last year he is a young player who is hungry to learn his trade and I feel both parties can benefit hugely from the move."
