Wigan Athletic boss Roberto Martinez blamed defensive injuries for their relegation.

The 4-1 scoreline, with two goals from Lukas Podolski and four assists for Santi Cazorla, illustrated Wigan's main failing this season - the 71 goals they have now conceded.

Martinez told Sky Sports 1: "We have conceded far too many goals. Going forward we have been magnificent, I think it's been our best season in terms of performances, but the injuries in the back line are something I have never seen before.

"To have four, five, even six players missing in the back line and our keeper affected with injury - our captain Antolin Alcaraz, Ivan Ramis out for the season, Ben Watson with a broken leg, (Jean) Beausejour, (Maynor) Figueroa...

"We have to have so many different partnerships and keep changing, and that caused us problems."
