Wigan boss Roberto Martinez has warned his players he will make changes to his struggling squad in the January transfer window. The Latics have been hampered badly by inconsistency all season and Martinez has questioned the character of some of his players after the disappointing home defeat to Birmingham on Saturday.
"There is inconsistency in our play and the reason is the lack of character that you need as a team," said Martinez.
"It comes from the character of individuals and whether they're the right characters we need at Wigan and it's something we're going to address - we'll make sure we do that. It's a painful lesson, but we need to make sure we learn from it
"When you see the two faces of our play, that is something I cannot accept.
"When you don't have that character, that know-how, it shows we need to increase the numbers and improve the squad."
