Wigan have completed the signing of French midfielder Mohamed Diame from Spanish side Rayo Vallecano.
Diame, 22, agreed personal terms and put pen to paper on a three-year deal at the DW Stadium earlier in the week.
Diame can make his debut in Saturday afternoon's clash with Manchester United and Latics manager Roberto Martinez said:
"Credit to Rayo Vallecano, we were not sure if he was going to be eligible. But they have pulled out all the stops at their end to get the deal rushed through in time."
