Wigan Athletic boss Roberto Martinez says it's impossible to replace Victor Moses.

Moses joined Chelsea last week.

Martinez said: "I think Victor Moses was such an influential player and such a special player for us I don't think you can replace him with another individual.

"You probably have to replace him with another way of playing in that attacking third or find another way to get the players to fulfil his responsibilities.

"As a whole I'm really pleased with the players we've got but I wouldn't be doing my job properly if I didn't keep my eyes open because sometimes in the last 48 hours you get opportunities you can't turn down."
