I'm a nice guy, so I'll explain to you why he is cheap in 5 easy steps.

1) Wigan have signed a new right-back. (Mario Melchiot)
2) Emerson Boyce plays at right-back.
3) Mario Melchiot has been appointed captain of Wigan.
4) Mario Melchiot will be Wigan's #1 right back.
5) Emerson Boyce will not be playing many games.
