Team news ahead of Sunday afternoon's Premier League clash between Wigan and Chelsea at the DW Stadium (kick-off 1.30pm).

New signing Ivan Ramis is Wigan's leading fitness doubt.

The Spanish centre-half, a £4million summer arrival from Real Mallorca, has a hamstring strain and heads two concerns for manager Roberto Martinez, with the other being James McCarthy (back).

Striker Victor Moses is in the squad despite interest from Chelsea, while Fraser Fyvie, Arouna Kone and Ryo Miyaichi are all in line for debuts.

Robert Di Matteo is considering handing Oscar his Chelsea debut.

Blues boss Di Matteo confirmed summer signing Oscar could be involved at the DW Stadium, despite having only arrived at his new club on Thursday after playing for Brazil for much of the past few weeks.

Fellow new boy Marko Marin remains sidelined by a hamstring injury.
